Depends on how they were attached. The door and the window at one point were two differant pieces, there not made together in 99% of the cases in newer units. Old wooden doors came as one piece and could not come apart.
Some use metal plates on the sides, some use corrigated fastners, but until it comes out or at least the trims pulled, there's no way to tell how it was attached.
