By window I assume you mean X11
In that case look at Perl/TK there are several great modules that can help you, that's the classic method although most people just do web interfaces now‎.
Also if you would like I could suggest some books to read that would help you a lot. 
I'm a pretty heavy Perl programmer my self and am always happy to help any one who wants to learn Perl.‎ 
One thing I will advise it seems pretty abstract at first but learn how anonymous references work in Perl because they are really the key to unlocking the true power of the whole language, I always consider it as the key piece of knowledge that separates Perl scripters from a Perl programmer.

Subject: Perl window question

Hi All,

I am trying to teach myself Perl. I am also trying to
get away from Zenity.

Any of you guys have a favorite method of creating a
windows from Perl that is SL7 friendly (meaning the
modules are available)?

Many thanks,
