Your question is very broad, so this answer will also be.

Generally speaking, tkinter doesn't play well with multi-threading. You can do it, but must make sure only the main thread interacts with the GUI. A common way to do this is to use the universal widget method after() to schedule handling of data going out to or being retrieved from background threads, typically via Queues, at regular intervals.
