You could use Godot (has a nice set of GUI widgets in addition to the game-specific stuff) or Lazarus (Free Pascal IDE) for instance. I did not use Lazarus much, but Free Pascal as a compiler and the language is nice and stable and supports a long list of platforms, generating native code (including cross-compiling between many different pairs of platforms). https://www.lazarus-ide.org/ https://www.lazarus-ide.org/
