Spearhead SDK or Radiant equivalent for Linux

Is there a Spearhead SDK or Radiant equivalent for Linux?

Idk if it's been asked before, but running radiant in wine causes weird actions with the arrow keys and probly other stuff.
The game runs fine for the most part in the same wine bottle, but last few times I've wanted to run the map editor
I can't get past the movement keys and mouse control being all weird and give up.
Maybe I don't have something/everything needed installed in wine to function correctly it?
Just thought I'd ask.
