First of all, if you have not signed up and gotten an account with Zoho, do it now. Don't wait to read more, click the link and get it done (that's not a suggestion).
OK, now that you have an account, you can read on. Zoho has a service called Zoho Creator, that allows you to create applications (you know those little web driven things). It's really cool and below is an example of something I did last night. I took me about 15 minutes to peck though and get it done - one table, a few items and done. And obviously, you can embed it within a web page. Once again, I give a double-thumbs-up for cool.
