Curiosity is very good
Too bad you didn't come here to ask! Ubuntu is great also.
During the netinstall, you can choose "desktop machine" or something like this(I've never done it).
If you want to install it afterwards,
and then for gnome:
Code:
apt-get install x-window-system gnome gdm
on the contrary, for kde:
Code:
apt-get install x-window-system kde kdm
Then you are prompted for configuring your Xserver (mouse,screen,..)
and that's it.
