Best programming language for planning

I’m making a development environment focused on games, and I needed some way to have people who know little about programming, write simple scripts for the programmers in the team to understand. I’m not looking for a object oriented approach. I need something like LUA or Python, something for the artists/writers to tell the programmers/engine-devs how they want an animal or sequence to work. I was thinking of just a text editor with syntax highlighting and letting them do whatever. But I would much rather an actual interoperated language, rather than gibberish that the developers can’t understand.

Keep in mind, the GUI for the development environment is done in JavaFX, so there are limitations to syntax highlighting and such.
