Well, you can, sort of. OS X's kernel is UNIX based, but OS X uses a totally different windowing system called Aqua. Traditional UNIXes use the X Window System. If you want to use the X Window System, you need to install an X Server. XDarwin is open sourced, and is the most popular X Server for Mac OS X. There are a few different ways to install XDarwin. From what I understand, using a tool called <a href="http://fink.sourceforge.net/

After installing an X Server, you'll need to install KDE. I'm not a big fan of KDE, but AFAIK there aren't any precompiled OS X ports of KDE. You'll probably have to grab the source and compile it yourself. KDE is huge, so it probably wouldn't be easy. If you want to try, start with a FreeBSD configuration...
