Does this exist??

Hi, I’m wondering if anyone can possibly help?
I’m after a plugin where the front end will exist of an input field, where the user will input a reference number, then press enter to show some data that relates to that reference number. This would lookup data that I have input into a table within the admin section or directly into SQL.
Does anything like this exist?
Many thanks in advance.
