I now got to the wxGlade RAD GUI creator - which looks very nice. It constructs GUIs in VB's style, and generates Perl code from them. But it's written in Pyton ! :-)

So far today I installed a lot of things...:

PAR ppm
wxPerl ppm
Python 2.3
wxPython 2.5

I never installed Python before... so thankfully everything went smoothly and wxGlade runs.
