Good advice overall. Bear in mind that there might be some differences between platforms. I think people are right to complain about the default look of Tk - it's ugly, no doubt about it. I like it, though. Tk is quick, simple, and available on practically every platform. I think there's a watch around here somewhere that can do Tk.

Anyways, the point I think I was trying to make: Perl/Tk on Win32 looks different than Perl/Tk on X11. Fiddling with the settings might not look as good on each platform.

Also remember that experienced users may have already adjusted their configurations a bit. I usually stick with the default look and feel. Less for me to remember. But don't let my laziness stop you from making Perl/Tk show an attractive appearance :-)
