Something like the following maybe? 
#!/usr/bin/perl -w

use strict;
use Tk;

my %density = (
  Some_Value    => qw(Something),
  Another_Value => qw(Something_Else),
  Some_More     => qw(Some_More),
);

my $mb = MainWindow->new();
$mb->minsize(qw(200 100));


for (sort keys(%density))
{
  my $keytext = $mb->Frame->pack(-side => 'top', -fill => 'none', -exp
+and => 1);
  $keytext -> Label(-text=>$_, -relief=>'ridge')->pack(-side=>'left', 
+-anchor=>'n');
  $keytext -> Label(-text=>"   ")->pack(-side=>'left', -anchor=>'n');
  $keytext->Entry(-textvariable => \$density{$_},-width => 15)->pack(-
+side=>'right', -anchor=>'n');;
}

MainLoop();
