That JS is unnecessary to the form iteslf - it merely
adds pop-up tips and a 'clear' button. The form is
functional without it (as far as I can tell)
You could reproduce it in anything from pure HTML to a
JWS Swing GUI, all you need to do is make a form/GUI
that looks like that. The values are the same as the
textual labels.

Then, once you have your information, append it to an
URL and make a POST to the target and you are there.

Of course, all this will be much easier in consultation with
the *author* of the page, who's email is clearly listed there.

What does the author have to add to this?

It is. Or rather, it is a smattering of JS to add 'extra bits'
to an otherwise fully functional HTML form element.

Learn how to program (or how to write HTML).
