How can I run KDE and Gnome on the same partition?

[Random21]

I did a fresh install of 10.04 and started customizing and adding my standard applications. When I went into admin.>login screen to see if I could change that crappy boot menu, I noticed that I have the option to boot into KDE. I am guessing this is due to amarok because that's the only KDE application I have. However, I decided to try it out. I booted into KDE and got the KDE noise, AWN showed up at the bottom, but the screen remained black other than that. I clicked on firefox and could use that, however, it had no title bar or decorations. I was wondering if it was possible for me to run both gnome and KDE side by side without issues.

tl;dr

How do I get KDE working on the same partition that I installed Ubuntu?
Will they play nice or will I have issues?

If it matters, I'm running 64-bit with Radeon HD 3100

Thanks for that. I have installed it and it works, but I have found that I will need to find a way to make separate startup applications. I don't have time to play with that now, but will maybe work on it this summer after the patent bar.
