GDScript is really easy to pick up, well documented and like any DSL created specifically for one job, it's straightforward without sharp edges. I've used many languages in games including C++ and I find GDScript a breeze. If you need something only another language has to offer, unless it's a big library, conversion to GDScript is usually the matter of a few hours at most. Otherwise for 2D another game engine I'd recommend is Love2D.
