A 👍 GUI example using Tkinter to prompt for multiple user inputs without doing successive AppleScript/cocoaDialog/etc popups.

Heavily cribbed from Jamf's iPhone ordering script https://github.com/jamfit/iPhone-Ordering

Requires at least a bit of familiarity with python and tkinter. Batteries not included.

The meat of what this script does is found in the submit() function starting at L147.
