No, you will need some client side code in order for this to work. I suggest a server side Perl script using CGI and HTML::Template and the JavaScript library jQuery for any JavaScript AJAX code.

Update: If you are unfamiliar with CGI and HTML::Template check out using CGI, DBI and HTML::Template (a mini tutorial with example code) from the tutorials section of this site.

Hope this helps

This is actually a rather straightforward programming task but only after you know how it all works; understanding either JSON or XML, Perl data structures, and the basic mechanics of Ajax (use a library like jQuery, don't write your own from scratch). If you've never done it I'd say the chances of doing it "ASAP" are slim to none.

Here is a small, standalone CGI + Ajax + Template -- CGI/Ajax example: lookup a value when a field is filled in. It does not meet your requirements but if you can get it running and use Firebug (a Firefox plugin) on it, you might be able to cut your learning curve down drastically. Having a working example helps a great deal when trying to learn this stuff.

No, in that Perl runs strictly server-side, not in the user's web browser. Doing what you want will require javascript code which will run in the browser.

Yes, in that, by using CGI::Ajax, you can do it without writing any non-Perl code yourself. CGI::Ajax allows you to write server-side Perl subs which are intended to be called by client-side javascript and then deals with the javascript glue required to make this happen for you.
