Don't forget Gnome and KDE also give you a development framework. Very likely the graphical apps you use are made with those development frameworks.. If you're enthralled with The Gimp, Galeon, Gaim, Evolution, XChat, Pan, Gnumeric, Abiword, MrProject, Glade, GThumb, Eog ... you should also be enthralled with Gnome. After all, would those applications have been possible if the developers only had XForms? Heck, even irssi uses a gnome library

(glib)
