I don't know what Gcam is, but it comes with a camera app.

I've never used Google Pay so I don't know.

The Google Camera app can be made to work fairly easily. Google Pay's NFC payment will not work in a useful way because the environment signature differs.

In fact, it's as easy as installing it through Play Store.
