I have never played with Par, (esp for Win32) so you may want to ask this as a separate node. One thing that I "think" will pose a problem, is if Par will also include the underlying Gtk2 c libs in a manner that will work on Win32. There are 2 levels of Gtk2..... you have the base c libs for each platform, then you have the Perl modules which interface those c libs. I don't know what Par does about the underlying c-libs, you will probably have an easier time running Par on Win32, for Win32.

Wouldn't it be nice if it was as easy as you suggest? You really should ask this on the Perl/Gtk2 maillist, the people who use it in Win32 frequent that list.
