Well, you have a couple of options here:

* Use Apache and mod_perl to write dynamic pages with perl.

* Use CGI.pm (or this tutorial)

* Use PHP again with Apache or your favorite webserver

as far as the rest goes, you'll want to design the logic yourself, to fit your particular needs. It seems at the very least you'll want some sort of graphical calendar. HTML::Calendar::Simple might be able to help you.

Good luck,
