If I handle a GUI on a single thread that is not the EDT, is it still thread safe?

If I create a GUI on a different thread, and make sure that any updates that happen to the GUI occur on that thread and that thread only- is it then still thread safe? I know this would be difficult to ensure, so in a way I'm kind of asking: Is there anything special/different about the EDT compared to other threads?

Keep in mind I'm not asking about good practices or other solutions to this problem, I'm asking if, on a purely technical level, if you basically treated a thread like the EDT, would the GUI created on the new thread be safe to use?

It is not thread safe because your processes are not the only one that read/write UI element. JRE is also read and write but it does it via EDT. So even if you read/write in the single thread which is not EDT there are processes that do it in EDT - so you end up with one UI element, few threads, no synchronization.
