I\'d like to write some interactive GUIs in Perl. I\'ve used TclTk but it looks dated. I\'ve written QT code for C++, but the PerlTk module hasn\'t had a release in several
I would probably use Gtk2, but Tk is definitely not dead. The lack of releases is due to the bugs being ironed out over the years. A lot of people still use it, and it generally works fine. (Tk's event loop is somewhat silly, but that is a detail that probably shouldn't concern you.) The only disadvantage is that your GUI looks like it is from 1996, but who cares?
(The gitk tool included with git showed that Tk GUIs look fine as long as they're useful.)
