I have done quite a bit with Perl/Tk, it is alive, well, very stable and for cross platform - no trouble, my users are on Solaris, Linux, HP-UX, AIX, OSX, BSD and Windoze. Tk is anything but Perl specific - Perl/Tk is a port of the Tk libraries originally used with Tcl. The only problem with Perl/Tk is that their are a lot of really nice (contributed not core) modules which will run on **ix but not on Windoze. About 40% (and declining fortunately) of my users are on ...doze so I am a little limited in some respects.

wxPerl looks nice, I played with it for a few hours - the entire wx scene seems to be quite active.

I have had a good look at Qt docs, and I may go there in the future, I will need to extensively test it cross platform before I can make a move though.
