Well, you could create a QGridLayout, and add multiple QLabel's to it, make these editable with setEditable(True), and whenever the user edits the label, write the value to a dictionary. When the application quits, you have to save the timetable to a file; here, json.dump could be useful (it converts a dict to json and writes that to a file). On application startup, you can load the data again with json.load (it reads a json file and converts the json to a dict) and set the values on the labels.
