Just use a simple black (or desired color) frame. 

#!/usr/bin/perl

# http://perlmonks.org/?node_id=1185809

use strict;
use warnings;
use Tk;

my $mw = MainWindow->new;

$mw->Label( -text => 'top part', -height => 5,
  )->pack;
$mw->Frame( -height => 2, -bg => 'black',
  )->pack( -fill => 'x' );

$mw->Label( -text => 'bottom part', -height => 5,
  )->pack( -side => 'bottom');
$mw->Frame( -height => 2, -bg => 'black',
  )->pack( -side => 'bottom', -fill => 'x' );

$mw->Label( -text => 'left part', -height => 5, -padx => 25,
  )->pack( -side => 'left');

$mw->Frame( -width => 2, -bg => 'black',
  )->pack( -side => 'left', -fill => 'y' );

$mw->Label( -text => 'right part', -height => 5, -padx => 25,
  )->pack( -side => 'left');

MainLoop;
