3D Object in GUI

Hey guys i was just wondering how i could show a 3D model in a GUI menu ? I have heard people talking about using Render Texture ? Would this be the correct thing to use ?

I will have a list of objects and when hoving over the listing in my gui then it will bring up a 3D model next to the name of it, the user will be able to veiw many different models but only one at the time.

Almost like the Skyrim menu.

I have the script to list my objects but i dont know how to render the model next to it and reference the model to the listing.

Could anyone please help ?
By the way i am using .js

Thank you
