[ZioMiP]

Hi to all...

I'm actually using Tkinter for my GUI... but I need to "put a piece of a 
web-page in a widget" how can I do?

which GUI module do you suggest me to use for do that?

or which GUI module do you suggest me to use at all?

I'm acutally using Windows Xp but I also use Linux...

I know that WxPython work only under Windows and PyGTK work only under 
Linux... there's some other modules?
