Hi, Patrick,

I'm not sure if I understood you correctly, but I think using Radiobuttons instead
of Buttons might be what you need.
You can assign a Tkinter variable to a set of Radiobuttons and define a certain value
for each:

    self.abortcode = StringVar()
    self.abortcode.set("5")
    self.button = Radiobutton(frame, text="continue on and update parcels",
                              fg='red', indicatoron=0,# makes the Radiobutton look like a "normal" button
                              value="3", variable=self.abortcode, command=self.quit)
    self.button.pack(side=LEFT)
    self.stop = Radiobutton(frame, text="Stop the update process",
                            fg='orange', indicatoron=0,
                            value="5", variable=self.abortcode, command=self.quit)
    self.stop.pack(side=RIGHT)

I hope this helps

Michael
