This can be made much simpler, by using Tk::Dialog.

use Tk;
use Tk::Dialog;
use strict;
use warnings;

my $top = new MainWindow(-title => "demo");    
my $save = $top->Button(-text => "Close", command => \&process_save)->
+pack();
MainLoop;

sub process_save {
    my $dialog = $top->Dialog(-title => "Save?", -text =>  "Content ch
+anged, save the changes?", -buttons => ["OK", "Cancel"]);#in real wor
+ld, you only display this, if the content changed
    my $response = $dialog->Show();
    print $response, "\n" #in real code, handle the response...
}
