There was an Oreilly book "Learning Perl/TK" out some time ago. I believe it is out of print however. I did pick up a copy at Amazon.com marketplace for about $7 used. Might be someplace to check out at least.
Master Perl/TK looks good. I have a copy however haven't had a chance to read it yet. Still ploughing through "Learning Perl/TK".
I believe "Learning Perl/Tk" is a subset of "Mastering Perl/Tk" (which is why "Learning..." is out of print with no further editions and is occasionally found in bargain bins).
