What is a programming language to make program with a GUI. I know there is a way to make a GUI using C in Windows, but I want to program with Linux and make my programs compatible with other OS's as well. Any recommendations?
If all you want to do is make a GUI, why don't you just use HTML?
Alternatively, if you really want it to be a more native app, maybe consider Java.

Who told you that you can't write a GUI app in C on Linux...
Also, for whipping up quick GUIs, there's wxPython.
You cannot create a GUI using the standard C library. You can make one with an external library though.
With OpenCV, it is possible to make a GUI, and there is a large community behind the project. You can find lots of code examples and tutorials on their website. In addition, you can use OpenCV for lots of other computer vision related things.
You could also use GTK+ to write a GUI for your program. It is very simple, and easy to use for beginners. It's more focused on graphics though, and if you want another functionality required by an external library, you might not be able to use GTK+.

Recently I learned Lua, we need it to co-work with existed C code(HTTP server).
From Lua books, we know that there maybe to way to make them co-working:
From Lua, you can wrap C code in share library(xxx.so) that Lua use require to import them.
From C, you can use existed Lua API to operate on lua_state, it's some trick but it works well.
I adopt both of them and everything seems great, by using Lua we can save a lot of time to implement our business logic. But I'm quite nervous about current architecture, although there was no serious problem in it, I always worried about it, if there was some thing happened, for example, serious performance bottleneck, memory related and so on.
Is anyone got rich experience in this, please give some some advice. Thanks.
Lua is designed to work well with both C and C++. The C API is meant for that.
You don't need to create and use shared libraries to extend Lua. It is the easiest way to extend the standard command line interpreter but it should be easy (if not easier) to link static C libraries for Lua in your own application.
If you want to see some examples of C libraries for Lua, see mine. There are many others.

I'm doing a sniffing project and almost done with it. We are now planning to create a GUI for it. We have written the entire network programming project in C language on Ubuntu 10.10 platform. Any idea/tools with tutorials regarding how to create a GUI for these C programs?
Will the language/tool/platform used for creating the GUI affect the C source code?
Thank you
There are different libraries for creating GUI applications in Linux.
There is GTK+, which is the native widget toolkit for GNOME and which has a C API. There is also Qt which has a very good C++ API, and which is also available for Windows, Mac OS X and other platforms.
I would suggest using GTK+ . It was natively written in C so compatibility shouldn't be an issue. I used this to help me learn it when i was messing around with it.

I am on the look out for a good software for browsing kernel level code written in C. I am currently using source navigator. Are there any better suggestions?
EDIT: I work on systems with both Windows and Linux (Ubuntu), so it should run on at least one of them, but Linux software is preferable.
This might not be what you're shooting for; it's less interactive than a dedicated tool, but I've found LXR to be very useful for providing a web interface front-end for browsing large source repositories. In each file, every symbol is linked to its original definition, so it's easy to dial down to exactly what you're looking for.
It was originally designed for indexing the Linux kernel source, and still does so here, (though I must say I'm not jazzed about the new AJAX interface...)
It can be run on any code base, though; not limited to the Linux kernel. And the web interface makes it easy to access from anywhere and from any system.
Visual Slick Edit does the trick for me.
Good tagging for big code bases, building, macros,light ui and support for many languages.
Unfortunately costs some $.
The reason I mostly wanted to switch from source navigator was that the project had closed down and the new project (Source navigator NG)seemed to be defunct(because the website etc. were down). But today, I checked and they had releases upto 2010. So they are probably still up and running.
Check it out, it has a good GUI and searching is easier than in cscope.
I use doxygen when I receive a big lump of code that I need to do a quick review on. You can use a special syntax in your source to make the doxygen output nice, but it does a decent job without.
netbeans works perfect for me
ctrl+click on any symbol will take you to the definition
then alt+left
very convenient for source code navigation
it's also cross platform

Today I've encountered a very good book : UNIX to Linux® Porting: A Comprehensive Reference
By Alfredo Mendoza, Chakarat Skawratananond, Artis Walker
This reminded me of the thing I always wanted to know. "Porting Linux apps to Windows". I mean porting native Linux apps to native Windows with no platforms involved.
If I can find any good book which explains this topic. I've lot of amazing linux command line tools in mind which needs a windows port.
Please point me to relevant articles/tutorials/books.
PS: please don't tell me to use linux emulation platforms like Cygwin.
Well, MinGW is possibly an API you're looking for, if you don't want to use emulation platforms. It provides compatibility between Unix and Win32 apps, and implements some of the win32 API. I'm using it myself for compiling the ns-3 simulator which is designed to run on *nix systems and Cygwin. You still need precompiler statements in there to access certain Win32 features where needed, or to modify macro / function names for cross-compatability. For instance, Sleep(..) exists but sleep(..) doesn't. There is also no usleep(..). I think this API just makes life easier for the application porter without any downsides.
MSYS & MinGW are two things that are required for porting apps from Linux to Windows.
Alternative way is to use Cygwin. But I don't consider it as 100% porting because it adds dependencies of Cygwin.

I've got a C++ app that ships on Windows and OSX. It communicates with our backend using TCP (encrypted with OpenSSL, natch). I'd like to throw up some speed bumps for folks who are trying to reverse engineer the protocol and/or disassemble the executable.
Skype does an excellent job of this, which is why you won't find a lot of apps that speak skype. Here is a really good read about what it does: http://www.secdev.org/conf/skype_BHEU06.handout.pdf
I'd like some ideas about how to accomplish similar stuff our app. Are there commercial products that make code harder to statically analyze? What is the best way to invest my time to accomplish the goals I've listed?
Thanks,
Some simple suggestions for OSX:
Prevent gdb from attaching to your program
http://www.steike.com/code/debugging-itunes-with-gdb/
(this can be worked around, but will keep some casual explorers away)
Have at least some of the code in your product stored outside the text segment of the executable, for example in data, or in an external (encrypted) shared library.
Minimally protect any sensitive string data by not storing it in plain text. Run "strings" against your executable, and if you see anything that might be helpful to someone trying to figure out the protocol, encrypt it.
GCC's -fomit-frame-pointer option can make debugging more painful (but can interact badly with C++ exceptions).
If I remember correctly Skype is using something similar (maybe they pay them to implement it in Skype, who knows) to "Code Guards" described in:
