I'm trying to write a programme, that is going to use nfc technology to transfer data between phones. The problem is, that I don't really know how to start it, what language or libraries should I choose? Or maybe there are any other technologies, that will allow me to transfer data via touching phones?

You can write your app following the Android-Beam guide
It can be written in Kotlin/Java Language.
Note that from Android 10, Beam feature is deprecated.
Instead you will have a new feature called Fast Share that uses Wifi Direct and other methods of pairing rather than touching.
