I want to write a simple program that opens a pop up window with message after a set time using the command line. The purpose is to use it as a simple alarm. For example, if I want to have a one hour coding session, I can use the program like this: python main.py --hours 1 --message "1-Hour coding session completed" & will result in a pop window in the top right corner displaying "message" and the elapsed time.

The program works as intended as of now on my system.
