WebGUI

WebGUI is a content management system coupled with an application framework. WebGUI is designed to make it easy for average businesses to create complex websites. The interface is web-based allowing those who control content to manage it online, rather than by IT staff. Features include shopping cart, subscriptions, forums, photo galleries, FAQs, link lists, blogs, SQL reports, a web services interface, and a very configurable user privilege and profiling system.
