You just have to make sure that all interaction with Tk is done from the main (gui) thread. Typically I use a bunch of variables to handle communication between Tkinter and the child thread, so the "Stop" button would set a "stop_child_thread" flag to True, whereas the child thread continually updates a "progress" flag that allows the gui to draw some visual feedback about the progress made by the child.
