KDE release 3 and earlier runs mainly on unix/X11 based platforms because the basic GPL'ed Qt(TM) library was only available for those platforms. Qt release 4 is now also available under a GPL license on Windows(TM) and MAC OSX (TM), which gives KDE release 4 the chance to also be available on these platforms.
I'm in the process of getting everything to build it for Windows.
