I've written this amazing Perl/Tk application. Here goes:

#!/usr/bin/perl

use strict;
use warnings;

use Tk;

my $mw = MainWindow->new();

$mw->Label(-text => 'Hello, world!')->pack();
$mw->Button(-text => 'Quit', -command => sub { exit } )->pack();

MainLoop;

Wow. Are you impressed? I bet you are.

Now I am ready to ship it. I want to deploy it such that someone can click on a URL and have the application downloaded and installed on Unix, Mac and Windows with a minimum of fuss. My end users may not have Perl and/or Tk installed on their machine.

What are the options? Is it possible to compile the perl interpretter, whatever modules I use and Tk into one bundle and installer?

Also, what are the licensing implications? Can I then charge people for my amazing "Hello Wolrd" application?
