Getting started with a GUI
 

I am thinking of porting my command line program to a GUI and wanted to get some pointers on developing a simple GUI. I am most familiar with KDE, so I want to start there. Where should I start?

kde has its own development environment called "KDevelop" (surprising, huh? lol) here's a link for you...

qt designer works too.......
also if you like gnome......glade is awesome.....

If you are interested in making your program cross platform then you should take a look at wxWindows. It is (arguably) the best cross platform gui library for any os. If you know Python, then you should also check out wxPython. It is very quick and easy to develop software using python. With wxwindows bindings, it will look the same on any os. Very cool in my book. If you want to use C++ take a look at Kdevelop or Glade. Kdevelop will be very similar if you are familiar with Microsoft Visual Studio. I'm also a big fan of Glade 2 because GTK2 is an excellent gui library. You already have the kdevelop link. Good Luck!
