I know @romainguy had a sample app (albiet old / out oof date at this point) which was using both Compose and Filament on Android: https://github.com/romainguy/sample-materials-shop
He might have a better idea of what it would take to integrate Filament into a Compose/Swing desktop app, but afaik it should be possible.
