Here's how I would do it in ES5:
function makeGui(doc) {
/*const*/ var title = doc.getElementById("title"),
url = doc.getElementById("url"),
input = doc.getElementById("input");
return Object.freeze({
get title() { return title.value; }
set title(newValue) { title.value = newValue; }
get url() { return url.value; }
set url(newValue) { url.value = newValue; }
get input() { return input.value; }
set input(newValue) { input.value = newValue; }
});
}
(I'd probably do more validation, but that would be a less fair comparison.)
