In what way? I think they are it's strength. I can whip up Perl GUI code faster in Perl, than anything else. There already is Tk, Gtk2, and WxWidgets which are cross platform. Most programmers don't like the very-high level uber-languages because they hide too much behind the scenes.

I suppose I have to agree, that it would be nice to make installing the toolkits a bit easier. Tk is a breeze, but Gtk2 can be a hassle on linux, and a real PITA on Win32.

What I would like to see is a java-like web browser plugin for Perl, so we can extend the GUI's into cgi.
