Sorry I think I am confusing you. The python code doesn't connect to any systems. Its a standalone code that is designed to spit out sql code that the users can then use to put in our system to look up data. Everyone using it is an employee
I think it is more clearer now. Technically speaking you can have your python script, that is basically some kind of assistant for writing SQL queries, and use some UI toolkit for python like Tkinter, PyQT, etc. to have a better experience for non technical users.
If you are sure that that's what actually meet your current needs, I think what I suggested is one possible solution specially if is just for looking up records and not modifying the DB, but you should discuss it further with any dev you choose to work with.
I hope you are able to find a dev for the job.
