Coghead allows any fool to create database-driven Web apps using Web-based tools and without writing any code. Basically, you configure your own app, publish it on Coghead.com, and share it with the community or not -- as you like. Coglets, which you generate using a simple wizard, expose small slices of your app (think forms and tables) that you can embed in other Web pages. Standard Web stuff, and not iPhone-native, but hey, very handy.
