Funnily enough, even with my own code made for running calculations only I will ever care about, I don't feel like a program is really complete until I've made myself a lame little GUI to drive it. The problem is always the same. The "ugh" factor when I try to make the program do something I haven't made it do in a while. If code doesn't have a pretty front end for me to click on, I'll run it much less frequently. (The second benefit, entirely unrelated to the article, is that it also allows me to make all my code incredibly fragile to bad inputs, right up until the point I make a GUI which is extremely fussy about inputs. Obviously, that could be done without the GUI, but it keeps me from spending to much time-- both in the sense of programming time and in the sense of run-time-- over-sanitizing inputs in the bulk of my code.)
