I have a sizeable perl script (an open source parallel text aligner) that is designed for non-techie users. I'm considering writing a GUI for it, and Tk seems to be the most obvious choice.
Now, this seems like it will be quite a lot of work, so before I start, I would like to make sure I won't hit a major snag.

I need the GUI to work on Windows, OS X and linux. Any portability issues to consider?
Also, is Tk compatible with PAR::Packer? As Windows doesn't come with Perl preinstalled, the Windows version of my program is a par-packed .exe, and I would like to keep it that way to make life easier for clueless users. Can PAR::Packer create a standalone executable out of a script with a Tk GUI?
