Thanks again to everyone who tried to help.
Michael, I especially appreciate your encouragement and chiming in to
point out that telling newbies to learn everything there is before
posting question was not helpful in getting more people using Python.

Hello, all.
Thanks to everyone who responded to my post.
I decided to make sure I had something that worked with what I have now
and used Curses to finish it. However, it turns out that the extra work

Guys, thanks for the various code examples for GPIO and the warning
about debouncing issues. I am still considering going the route of more
complex wiring and doing it a more traditional GPIO way.

Ah, but in reality "keystrokes" is not simple at all. Keyboards and
input handling is a very me
That was the impression I got reading some comments people made online
and doing research, so I focused on tkinter. As I mentioned in the 4th
sentence of the post you quoted I discovered that was not the case, but
by then I had already done some work on the tkinter script so I kept with
it.

It appears that one of my posts was cut off. It contains my script but
none of the lengthy text in front of it.
To summarize, my set-up consists of three "massive arcade buttons" from
Adafruit. one red, one blue, one yellow. They are connected to a Kade

Michael, your assumption is correct. To quote my original post, "and I
want this working on a Raspberry Pi." Doing a superficial look at curses

Laura and Gary, thank you for your replies. I have three physical
buttons connected to a Kade device emulating a keyboard. These buttons
control an LED light strip. So there is no screen, so a GUI did not cross
my mind. I thought it made sense as it is easily done by other scripting
languages

Tkinter runs on raspberry pi.
Get it installed, and then run this program.

root = Tk()
prompt = 'Press any key. Remember to keep your mouse in the cyan box. '
lab = Label(root, text=prompt, width=len(prompt), bg='cyan')
lab.pack()
