How to make a program that can open models?

[TheAmazingSnivy]

Do you know anyone who is good at programming? I would still like to make the program. My idea is to make modding tools for the games.
Plus, if they make another game with the same file extension, all you would have to do is open them with my program. (In theory, of course.) Right now I want to start small, just a program that can open DAEs.
