How can you make a build menu with interactable objects, and a material gathering system?

The main catch is I don't know how to script, so I have no idea how to handle this. I've edited scripts before, but not one as complex as this. On top of that, I'm not editing a script: I'm trying to write one. Another problem is how do I have gathering resources happen in the first place, let alone, linking it to the build menu so it recognizes you can build the item. Also, when the objects are put down, how can I make it so you can interact with it, and it'll create a GUI that makes it so you can make more items to allow crafting more things? This is really confusing, and I would deeply appreciate it if someone helped. Thanks :D.
