I made a script for managing a Gopher and a WWW website at the same time, in the same machine with your Mystic BBS. Its called Gophlog and you can find it at Another Droid BBS and also at FSX (as soon its being hatched).
You can take a taste here:

It doesn't sets up your gopher/www server... it justs maintains the text/files and interprets them to valid gopher/html syntax. You can use it for just maintaining a Gopher site, just a HTML site or both simultaneously.
You write your pages "code" in a BBCODE style and when you are ready, you export the site to gopher/html syntax.
Don't hesitate to ask if you have any questions on how to setup the script and use it.
