You're absolutely right. I indeed misread "like better" as "is better". And because I like Tk that much, I immediately jumped in.
runrig already mentioned that the Learning/Tk book is kinda useless and Mastering Perl/Tk is much better. I wholeheartedly agree. Though I'd like to add that after reading the latter, having the perl/Tk quick reference guide available is darn handy.
... and Glib and Gtk2 and X11::Protocol all to get into graphical front ends. Not really for starting out simple GUI apps though.
Enjoy, Have FUN! H.Merijn
