I have been using the following scheme:
  - Pass the root object to the thread object when creating the object
  - Define a event_handler: root.bind('<<SomeEvent>>', evt_handler) in
    the main thread.

  - When the thread has done something that the GUI part should now
    about, signal an event in the thread:
        root.event_generate('<<SomeEvent>>')    (no other arguments)

  - Call a method of the thread object in the event handler e.g. to get
    some data from a queue object.

This ensures that only the main thread accesses Tkinter-related things.
