Questions about porting Qt app from Github (thinking about porting)

Source from GitHub that is free with GPL - https://gitlab.com/tp3/Entropy-Piano-Tuner.

About the original GitHub source code.

The source contains code for multiple target platforms
There's code to build two libraries that are already in base system
To compile some changes are necessary to some config files
It's uses Qt6, xorg, qmake, mate, gl
Compiles with QtCreator on latest GhostBSD (FreeBSD 14.3) or from shell with qmake and make
Because of the "inside" libraries some LD_LIBRARY_PATHS needs to be added to run, ie startscript required

Having never done a port for FreeBSD before I am thinking this could be as easy as creating patches with diff between GitHub source and the changes required to make it run.

What is best practice?

Is it possible to make fetch the original GitHub repo as a tarball into distfiles (Without a GitHub account?)

How will the patches get to the ports - are there PATCH_SITES (bsd.port.mk) available?

Could a beginning Makefile look something like this? (using /usr/ports/audio/fmit as example)
