HTML is, for fairly good reason, not able to execute code on the
machine it's browsed from, or anywhere for that matter, except in the
Javascript/Flash/etc sandboxes. (Which are also forbidden from
executing code on your machine)
So you will need to do something like CGI..
However, you don't need a web server to be installed for that.

Your Perl script can quite happily open up port 80 (or another,
non-reserved port) and listen for HTTP requests upon it.
(In effect, your Perl script becomes a stand-alone web server.)
