I'm not sure what application you mean (a Treehouse course?) but the answer is probably no.

The DOM is how Javascript interacts with the document in the browser. It's possible to write a program in Javascript without the DOM but it wouldn't influence anything the user can see/interact with. Think of a tree falling in the forest when no one is around.

After your clarification: technically, no. JQuery still interacts with the DOM.

Yes, you can most definitely build it using JQuery and not call vanilla JsvaScript methods like getElementsByClassName, but I don't think it's a good idea. If you don't understand how Javascript is working with the DOM, it's going to make it really challenging as the programs you write get more complex. JQuery is an abstraction layer ONLY - make you sure you get what's going on under the hood before you charge ahead.
