No, normally KDE, which is based on Qt, supports running GTK and GTK2 
applications as well. Also Gnome (on Ubuntu) might run Qt applications, 
too (at least if the Qt libraries are installed).

I myself use a Linux laptop without Gnome or KDE, but I can run GTK, 
GTK2 and Qt applications on it.

There is no pure X widget set in Lazarus, you always need to decide 
whether you want to run Qt or GTK2 (GTK is deprecated today). You might 
want to read about the two on Wikipedia:
http://en.wikipedia.org/wiki/Qt_%28framework%29
http://en.wikipedia.org/wiki/GTK+

If you want a Object Pascal GUI framework with as less dependencies as 
possible (only X), then I'd suggest you - as Graeme did - fpGUI, but you 
need to keep in mind that this isn't VCL compatible like the LCL is.
