Do you mean inline or do you create the other dialog definitions in other
classes?

class Dialog1(TopLevel):
    button1 = Button(.... command=self.doButton1)

    def doButton1(self):
    # do stuff here

class Dialog2(TopLevel):
    button1 = Button(.... command=self.doButton1)

    def doButton1(self):
    # do stuff here

You can use parameters to the constructor to explicitly pass 
a reference to the calling class or navigate the parent 
heirarchy maintained by Tkinter.
