In this latest offering from the IBM developerWorks site today, you can learn how to, with the help of a bit of PHP and Derby to create a CMS.

Learn how to build a simple content management system (CMS) that can be used to create, maintain, and submit a sitemap to Google automatically. Page content is managed through a database using PHP and a Web browser. When the system's content changes, the system creates and submits a sitemap to Google, speeding up the process of getting your new and updated content indexed.

Firing something off to an external resource is something I know I wouldn't mind MySQL doing (anyone know if you can?) - especially when you can directly notify Google of an update to your site. You'll need to know a bit about PHP (obviously), have done some database work, and have access to a server with Cloudscape and Java installed.
