you might want to look at the mailing list archives and at the FAQ,
specifically at these two entries:

  http://live.gnome.org/GTK2-Perl/FrequentlyAskedQuestions#main-loop
  http://live.gnome.org/GTK2-Perl/FrequentlyAskedQuestions#io-poll

in short: you are writing a GUI application like a console application;
the short answer is: don't.

ciao,
