Well, I'm assuming that Perl and text files work, since this forum is up. Why not make one using that? You could just make the test file read/write protected and/or encrypt + encode it.
I'm also fairly sure PHP is working here since index.php is working just fine, why not whip up a poll script in PHP and maybe MySQL? I could make one if you'd like but you seem to know what you're doing with PHP by the looks of the website.
