Simple Button Event Handling, changing properties (tkinter)

from tkinter import * # Import all definitions from tkinter

class ProcessButtonEvent:
    def __init__(self):
        window = Tk()  # Create a window
        btOK = Button(window, text="OK", fg="red", command = self.processOK)
        btOK["text"] = "Hide"
        btOK["bg"] = "red"
        btOK["fg"] = "#AB84F9"
        btOK["cursor"] = "plus"
        btOK["justify"] = LEFT
        btCancel = Button(window, text="Cancel", bg="yellow", command = self.processCancel)

        btOK.pack()  # Place the OK button in the window
        btCancel.pack()  # Place the Cancel button in the window

        window.mainloop()  # Create an event loop

    def processOK(self):
        print("OK button is clicked")

    def processCancel(self):
        print("Cancel button is clicked")


ProcessButtonEvent() # Create an object to invoke __init__ method
