You have the right idea. For small callbacks, I usually create an anonymous sub: 
my $button = $top->Button ( 
                           -text => "click me",
                           -command => sub {system "myscript.pl $filen
+ame"}
                          )->pack();

[download]
and then have myscript.pl read in the filename from the command line.
