You need to install a webserver on your computer.. use IIS, PWS, or even Apache for Win32..

Next, write a HTML form as so..

<form action="launcher.pl" method="post">
<input type="submit" name="sub" value="Run this!">
</form>
[download]

on your page..

Inside your launcher.pl CGI script (yes, you've writen a CGI script now), execute the Perl script that you want using exec or system or backticks like so..

#!c:/perl/bin -w
use strict;
use CGI;

my $q = new CGI;

my $path_to_program = "c:/perl/myprog/prog.pl";
my $return_value = system("c:/perl/bin/perl.exe",$path_to_program);

# this is the actual execution of the script. 
# now you can put a message to the user
print $q->header; # send correct header, text/html
# put HTML here

It might be best if you restrict access to this script to ONLY your machine..
