I wanna create a Gui like windows operating system for Linux. The latest Linux versions are user friendly .But I want to do this as a mini project. So my aim is a simple gui for Linux.

And there are so many gui development tools like gtk, Kdevelopr, Qt/...etc.
Which one I've to select , which one is better for my need. Presently I use Fedora 11.
Wait for a reply...

thanking you
