Creating such a simple CMS is not that hard, there are a lot of tutorials on the net for using forms and a database to update and display information. The only big concern I have had is security but I've simply taken some small precautions to prevent the client from killing his own site and password protected the folder to prevent any unauthorized access.
It's fast and lite. Add in the WYSIWYG editor of your choice (use MOStlyCE) and your set with easy-to-use editing for your client.
If you need a blog aspect, go WordPress -- but make sure you install the various SPAM filters, etc.
As I understand it no mysql/PHP driven CMS publish static html
Hate to sound like a broken record, but WordPress *does* create static pages.
As for making the extension HTML rather than PHP, it's been done (and they have info on how to do it in the codex), but I've never done it myself - never had to.
