Visual Perl Tool for GTK/QT development?

Robin Smidsrød asks: I'm planning on making a full multimedia system with my Linux-box. In this process I need to make a GUI for selecting which files to insert into a playlist for my mp3-player. Since I've done a lot of coding in Perl, and both QT and GTK-bindings are available, I'd like to program my GUI in perl and GTK/QT. The program isn't really very advanced, but are there any tools available for (at least) setting up the GUI, or maybe a complete IDE? I've done several queries on Altavista, and I've searched Freshmeat too, but no luck. Can anybody help me?" Heck! Microsoft has Visual Basic, why can't we have "Visual Perl"?
