FYI -- PAR works great on Win32 and is free. You can download it via ppm, but it's an old version that does not have the "--gui" option to disable the console for GUI apps (such as Tk). To get the "--gui" option, you will need to use the version of PAR in CPAN, which will probably (if I recall correctly) require MSVC++ to comile the module. I'd look at PAR before paying for something.
