Tk is only ugly if that's the way you like it.  You have a
full set of themed widgets available now that give you
native look and feel, with all the same dynamic control and
general ease of use that Tk has always provided.  All this
on Aqua, Win32 and X11 (even Windows/CE).  Some screenshots
of Tk apps that try not to be ugly:

Tk on Win/CE (I know that the Perl/Tcl::Tk use this too):
