If I want to close all the windows, I can use the application's
"Quit" or "Exit" command, or whatever the platform calls it.

(Note that if there is a separate instance of the application
for each window -- as was suggested earlier -- then you don't
have that option, and you have to close them one by one
anyway.)

Which is *exactly* what I said you would have to do in
Tkinter! Each widget creation requires a separate statement,
with the parent passed in at each step. This is nowhere
near as convenient as the nested function call style.
