I think the Tk::ExecuteCommand module is what you might want. Try running the following script and see if you get ideas. 
#!/usr/bin/perl -w
use Tk;
use Tk::ExecuteCommand;
use Tk::widgets qw/LabEntry/;
use strict;

my $mw = MainWindow->new;

my $ec = $mw->ExecuteCommand(
    -command    => '',
    -entryWidth => 50,
    -height     => 10,
    -label      => '',
    -text       => 'Execute',
                                  )->pack;
$ec->configure(-command => 'date; sleep 10; date');
$ec->execute_command;

MainLoop;
