Which version of MSFS are you running?

You could use a Screenshot of the MSFS GPS window and use it to create a TB Tab.

To make a TB tab for the GPS, you could take a screenshot of the GPS in the game, and paste it in MS Paint. Save it Then use that as a background and then create buttons to send for the GPS functions.

No, you can't alternate between the two probably. TB is designed to not receive the Windows active focus. That just means you can't click on it or Alt-Tab to it, or make it the Active Window.
