Form building with my own database

I need to build a large, elaborate form with required fields and some JavaScript validation. I can do this by hand but would much rather find a form builder that would make it faster and easier. Every form builder I've found so far uses the developer's database. I need something I can use with my own database. Does anyone have any suggestions? I have, or can write the back end scripts to handle the data.

Hi RedBopete, I would recomend Coffeecup's Web Form Builder.

:)

Also http://www.simfatic.com/ - a bit rougher presentation wise vs coffecup but I found it better for what I was trying to do when I used it last.

Thanks, everyone - I will check those both out!

I wanted to add an update to anyone interested in this topic. I decided to go with Simfatic, and have been very happy with the results. It has more features and options than I'd anticipated, and was very easy to use. I did run in to a few issues, but the author was very responsive.
