Hi, your best bet to learning is just to start writing simple programs, and hack your way through the "underbrush". I always go to the website groups.google.com which has alot of code examples just for the asking.

For example if you want to know about a tabbed notebook, go to groups.google and search for "perl Tk notebook". You will get alot of code samples to get you going. Do you want to know how to use a button? Type in "perl Tk button".

There are some fine points which only come with experience, (and repeatedly making the same mistake)...like how to make proper callbacks, reusing widgets to avoid memory increases, and packing widgets well(use alot of frames :-) ). But you don't learn until you jump in and start. Also if you go to safari, you can download an html copy of Mastering Perl/Tk so you can cut'n'paste and run code as you learn. Thats a good book.
