There's nothing built in that does it. One would have to do this with some custom javascript/jQuery. jQuery has functionality to show and hide things based on the state of other things.
Note that nothing is going to give you a cascading selection process where the secondary options are different based on the initial option. i.e. you're not going to be able build a product by progressively selecting radio buttons or dropdowns.
I would recommend revisiting how you are organising the categories, products, models and options. There's always a way to make it fit and it's not always the obvious way.
