Yes Tk is available in Perl.

It might be worth your while looking at the Tk widget demo
program that installs with Tcl/Tk.
Its written in Tcl but does show the various config settings
for most of the widgets.
Alternatively buy Tcl/Tk in a Nutshell from O'Reilly, its a
very good reference to Tcl including Tk.

Try my beginners tutor at:
Specifically the OO page, the event Driven page and the
Case study. They all explain and/or demonstrate classes
and OO programming. There is also a little bit of Tkinter
in the last two but not very much.

Normally you create something called a "dirtyflag".
Everytime an edit function changes the contents ypu set the dirtyflag to
true. After a sve you reset it to false. Then if they hit Save you can do:
# save it here
The textwidget may have something similar built in I don't remember,
but I doubt it.
