What is a hash map? From your title, I gather you want to dump your table into a Tk widget. There are many types of widgets. Look at this: 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::Table;

my $mw= tkinit;
$mw->geometry("400x400+100+100");

my $table = $mw->Scrolled('Table',
                       -rows => 20,
                       -columns => 50,
                       -scrollbars => 'osoe',
                       -takefocus => 1)->pack;

my %widgets;

for my $row(1..20){
  for my $col(1..50){
    $widgets{$row}{$col} = $table->Button(
               -text=> "$row - $col",
           -background => 'white' );
           
    $table->put( $row,$col,$widgets{$row}{$col} );
  }
}

MainLoop;
