I only have a clue as to what you want to do. The following snippet, shows you how to programatically modify menus. Modify it to add more entries. 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;

my $count = 0;
my $mw = tkinit;

my $menubar = $mw->Menu(-type => 'menubar');
$mw->configure(-menu => $menubar);

my $menu = $menubar->cascade(-label => '~File');
$menu->command(-label => '~New');
$menu->command(-label => '~Open');

$mw->Button(
-text    => 'Push me and look at the menu',
-command => sub {
my $state = ($count++ & 1) ? 'normal' : 'disabled';
$menu->cget(-menu)->entryconfigure(2, -state => $state);
}
)->pack;

MainLoop;
