So you should be reading your controls in the callback for the
'clicked' event (the sub{} block below).

The documentation section of the Gtk2-Perl website [1] has a tutorial
[2] that comes with live code examples that could help you work out
the rest of your question above. There's also the demos/examples in
the Gtk2-Perl git tree, as mentioned by Emmanuele in IRC[3], that will
have examples of callbacks for the 'clicked' event.
Thanks,
