Need help making a new app and querying

I was thinking of building a webapp where I can search for someone based on their name/phone number/interest and it will display all people that match this data.
The data can be stored in a google sheet/airtable.

Basically think of it like a phonebook on the web for my company where I can search
How do I build this?

You have to create the connections with google sheet/aurtable by API.
