I have been working on a GUI chatterbox client on NT. I started with Win32::GUI, but I think that some of the features I would like just weren't there (yet?). However, I did find the module easy to program. If you're interested, I've included my code here. BTW, this make use of zzamboni's PerlMonkChat.pm (thanks zzamboni!).

The code has been moved to the Code Catacombs -- please check it out: Win32::GUI Chatterbox client

Cheers,
Shen
