No. The GUIs I know of (GTK, Android, etc) are all single threaded and any
other threads which need to use the GUI need to queue a request on the GUI
thread.

For example, in Android, you can define a Handler on the GUI thread which
receives messages from other threads:

https://developer.android.com/reference/android/os/Handler

I tend to use:

https://developer.android.com/reference/android/os/Handler#sendMessage(android.os.Message)

to send messages from the other threads to the GUI thread.

No. In the GUIs I am aware of, the main GUI thread _is_ the event thread.
