The discussions from wchiquito's comment are an interesting read, but following all the links is time-consuming.

Bottom line: There will not be DriveApp version of getFolderByPath(), so you will need to roll your own. In the Google+ group, Faustino proposed a work-around and Eric improved it. Here it is, with an added check to allow paths that start with "/".

function getFolderByPath(path) {
  var parts = path.split("/");

  if (parts[0] == '') parts.shift(); // Did path start at root, '/'?

  var folder = DriveApp.getRootFolder();
  for (var i = 0; i < parts.length; i++) {
    var result = folder.getFoldersByName(parts[i]);
    if (result.hasNext()) {
      folder = result.next();
    } else {
      return null;
    }
  }
  return folder;
}

With that, you can simply do myFolder = getFolderByPath('Main Folder 2/Folder 1');. You will end up with a DriveApp Folder instance.
