tkinter is an optional compiletime choice. Reader needs to be told they may have to install it

e.g. wsl2 doesn't come with tkinter as part of its python3, you have to sudo apt install python3-tk. Maybe "you may have to install this with your package manager" in a footnote?

I had something similar, I just made a note in my 'ReadMe' for later. On a related topic, I am thinking later on I might try and setup a docker dev environment or maybe a script in a makefile to ensure all dependencies are set (or maybe compile into an executable).

I'd vote Make since it's friendlier for the uninitiated than Docker. Of course you've got to bootstrap them to having Make/Docker.
