Hey @Ivory Leopard!
If you consider using Google's Apps Script it means you have some basic understanding of a programming language, you'll need to use their REST API with $(urlfetch). That said you should be able to do most of what you want with $(eval). Also check out the forums, we covered a lot of topics, some will help you, I'm sure of it.
We won't help further as we're not Google's support, and it's not our job to teach programming languages.
Edit: I've been told by a couple of friends my answer might sound harsher than I meant it, if so I'm sorry, this wasn't my intent. If you need resources to learn a language to make Nightbot commands, you'll need to learn JavaScript, you can start with W3Schools' course on JS, or MDN's, I recommend starting with the first one, and use MDN's reference once you gained enough knowledge.
