python - How to save data from QSpinBox into variable after clicking button?

Question

I'm in the process of making an alarm clock GUI. My GUI has options to "Create Alarm", "Remove Alarm", and "View Alarms". In the Create Alarm option, I made a QDialog window consisting of 2 SpinBoxes (for a 24 hour clock) with a Cancel and OK button.

I'd like to have the user select the time they'd like, say 10:30, then to have that specific time saved into a variable and/or append it to an empty array after the user presses the OK button. So then I could hopefully carry that variable/array over into the "Remove Alarm" and "View Alarms" portions. Is this possible or should I go about it a different way?

Here is my code so far:

from PyQt5.QtWidgets import *

# Start with empty array that will store appended alarms

alarms = []
