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();

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
