Simple Constituent Creation Web App?

Hello Tess Web API gurus,

Has anyone developed or used a simple web app that uses the Tessitura Web API to handle only the creation of a constituent record with name/address/email and minimal extra data such as date of birth and interests?

I am investigating ways for us to enable customers to streamline their own constituent record creation on PC terminals (or tablets) in our lobby. 

Cheers,

Nicholas
