Dynamic pages to be linked?

Ok I am sorry if this was already posted, but I have been looking for most of today for the answer to this.

My site uses a single page to render all pages - index.php and the urls are in the form of index.php?pid=27

What I need is the ability to lookup in the database that pid of 27 relates to the "About us page" or whatever it relates to, and then that be in the list of possible links when I click the "browse server" button?

Any help would be appreciated.
