Is it possible to mount more than one image AND text on a Tkinter button?
Or, is it possible to put a FRAME containing images + text on a button?
I want a big button containing multiple widgets that, when taken together, fully describe the option the user will be able to choose.
I appreciate any suggestions!!

Strictly speaking, no, it is not possible. 

Or, is it possible to put a FRAME containing images + text on a button?

Yes, though it probably won't work on OSX. It would probably take you less time to actually try it than to type in the question on stackoverflow. A little research goes a long way.
You can also simply not use a button. Just use a frame or canvas, and set up bindings on the container and/or it's contents to react to a button click.
