Design and code simple website with php and mysql

We want to update a current web page for a independant professional, medical doctor and psicologist. It needs a fresh design and update, and good practices for SEO. The current page only has 7 pages. We want to add to the web a dynamic part so the owner of the page can update or add articles. Joomla is too complicated for him. Only a simple form and administration page so he can publish, delete and add articles to a concrete part of the site. This should be implemented with mysql . Also can be cool to integrate some "online doctor" so visits can make questions, and the doctor will publish answers, and also be able to delete posts. Like a forum, but more simplest.
