I'm not an expert user on frontpage but I'm not really sure microsoft products work really well with apache or unix/ linux products in general. And as for using php/ perl tags, these are not tag-based languages. Coldfusion is. Maybe it is better to set this up on a Windows platform with IIS/ SQL server or access or even MySQL for windows.
The most common layouts for webservers with scripting or programming languages are:
1/ apache/ php/ perl/ mysql on linux or unix
2/ apache/ tomcat/ j2ee/ oracle (or whatever database) on linux or unix
3/ IIS/ ASP/ SQL server on windows
4/ IIS/ Coldfusion/ SQL server on windows
If you're simply using Frontpage to generate the content, I wouldn't think Apache would have any trouble rendering it, as long as you tell Apache where the content is, and all of the internal links resolve properly.
