Creating a Real-Time generating Star Wars themed space window

I have started to create my real-time enviroment generating Star Wars space window.
The goal of the project is to have a software that is as if you are looking out of a window on a Star Wars spaceship.
I have a couple things I would like to include in my software and those are as follow:

  • Randomly generated spaceship flying by (one of 15 models I already have)

  • the occasional planet seen

  • the ability to close the window (A black shade just slowly comes over the screen)

  • occasional group of stars floating by

  • the ability to have multiple windows that show the exact same thing but from a different angle

I am not sure how to begin with blueprints and I already have all of my models and textures in place.
Thanks!
