If you really want to get a Windows look and feel, you'll find that Tk, while considered the de-facto GUI standard, will not give you the sort of widgets you may be accustomed to. For this reason, you may want to check out Win32::GUI as well, which uses native Win32 API calls to generate dialog boxes and common controls.

update(doh!): i should really get into the habit of reading people's replies to questions before repeating what has already been said :)
