GUIs For Script Languages

Various GUIs exist to help developing programs in the various scripting languages.

Visual-Tcl is a tool that's supposed to turn Tcl into the 'visual basic' of Unix systems.

Few IDEs And GUI Debuggers exist that support Perl and Python. 'ptkdg' is a nice Perl/TK GUI Debugger. Activestate's IDE is considered a good one for windows, and their work on a cross-platform IDE (Komodo) will hopefully create a good IDE for Linux as well.
