Simple App to pull xxx fields from xxx DB table and put them on user profile?

I have a DB table with a User ID # field and lots of other fields (just basic text / number data)

I want an EasySocial App such that if on a User Profile page, it'll check that DB table and return the specified fields from the table relating just to that particular User ID #. (So not all the fields, just the ones I can hopefully specify in the back-end App settings)

My guess is that's nothing too advanced (although beyond me) - Is this kind of thing already produced and available anywhere... or if not, anyone know who could put one together?

Thanks!
