Is it possible to set the price dynamically?

I have a product configurator tha has lots of options to get the product you want, then it wil create a new price using javascript. Even tho I know its not save to set a price with javascript I need somthing for now that I can use instead of the tv, later I wil try to create the javascript part also in php.

But my question is : is there a way to not use a tv as price? but hook in the add to basked to change the price?
