CRM is build on and with Joomla! framework, the number two php framework in the world. We are very exited about Joomla! as it will give you an easy Content Management System (CMS) and a great structure to make use of applications that otherwise are hard to combine with website presentation.
Please keep in mind that if you make any changes to CRM to use the Joomla! & PHP guideline to assure a proper working of the system. DIY fancy programming might create security leaks in your solution, short or long term.
