>So, to make life interesting and things more simple, the plan is to gradually redo all three or four of these apps >in python/Dabo.

Two items:
1. I was able to get Dabo to run with wxPython 4.2.1 and python 3.11. Waiting for python 3.12.
2. I have been playing with "flet" which is a python flutter. Works well but is missing controls and you may have to write your own. But is worth the time to review.

BTW you can find wxPython linux wheels at:
https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-22.04/
