They created a touchscreen GUI in tkinter with more-than-trivial behavior to use as a frontend for input for a device they created. They were able to describe what they wanted, and in less than two hours have it working. This is someone with no software experience.
Three years ago, if I had been asked to create something like that, it would have taken me more than two hours, just because I've never used tkinter and would have to spend time reading the docs and figuring out how to make the different input boxes and laying them out properly.
I looked at the code, and no, it's not great. It's not designed "well" and isn't very extensible. But it works for him, doesn't need to be extended, and all in half a morning.
