GEANT4 for a Course Project in Deep Learning

I am taking a Deep Learning course at the university I work at and as part of that course we need to do a project where we apply Deep Learning to a problem in any domain. I am interested in Particle Physics and wanted to try something in that realm.

I would want to do something similar to what has been done in this paper ( Basically just make a “toy” neutrino detector experiment with a sphere of scintillator attach PMTs around it and simulate some background radioactive decays and inverse beta decay signals.

How hard would it be to run such a simulation in GEANT4? I am a C++ developer, so the language and setting up GEANT4 on my computer isnt an issue.

Any insights, or similar examples would be greatly appreciated?
