Widget for Dolphin-based Socail Network

I have am in the process of starting a social network site using Dolphin software. I would like to be able to create a program that takes some basic information from users (location of residence, work place location, usual mode of transportation, salary, etc) then queries the appropriate database for each question to find an appropriate value, then puts that output into a formula and computes a final value. I already have the above formula, as well as, all the necessary information for the databases. After this value is computed I would like to be able to make it subsequently modifiable based on user generated inputs, entered through some kind of widget.
