You should try again. gmpasso's link above to http://wxperl.sourceforge.net/ has a Download section with binaries that worked perfectly. I have been developing Tk stuff for about 2 years but decided to have a look because of the comments in this node. It is really an impressive piece of work. I am going to invest the time to learn it because the demo's showed examples working well with threads and multiple processes. It appears much faster, and it has a better looking interface and a richer widget set than Tk. I built out the first example and it is completely different from how you build a Tk gui. (Not worse, you just have to think more OOP.) WxPerl really needs an O'Reily book on it. I used ActiveState 5.8.0 and the wxPerl unicode version from http://wxperl.sourceforge.net. I also ran the script through perlapp and it produced a smaller executable than Tk and ran just fine. I am hooked.
