If nowhere else, make a post on NoStupidQuestions and I’m sure there’s a few people that will help. I made a reply here suggesting raspberry pi os as a good starting point. No command line skills needed and quite a bit of software is available free from Debian (Linux which raspi os is created from).
The user interface is similar with a start menu etc.
If you’ve got a spare PC, I’d use it as a guinea pig system first before moving onto the main system.
And it probably needs to connect using WEP
