Have a look at the SimpleDialog module. A usage example is at the end of the 
file:

$ grep __main__ /usr/lib/python2.6/lib-tk/SimpleDialog.py -A1000
if __name__ == '__main__':

    def test():
        root = Tk()
        def doit(root=root):
            d = SimpleDialog(root,
                         text="This is a test dialog.  "
                              "Would this have been an actual dialog, "
                              "the buttons below would have been glowing "
                              "in soft pink light.\n"
                              "Do you believe this?",
                         buttons=["Yes", "No", "Cancel"],
                         default=0,
                         cancel=2,
                         title="Test Dialog")
            print d.go()
        t = Button(root, text='Test', command=doit)
        t.pack()
        q = Button(root, text='Quit', command=t.quit)
        q.pack()
        t.mainloop()

    test()

You can invoke it with

$ python -m SimpleDialog
