Don't worry, you can do this in C# or Python as well. Just structure your small, gradually growing proof-of-concept and soon-to-be-finished-product program correctly. No classes! Or at the very least a few monolithic ones, which cannot be instantiated. Use static methods whenever possible. I have never ever ever done this.
