CreateScene() - otherwise this looks like an accessor, and I wouldn't know it
was creating again and again.

Could you add comments, so we know the use theory?

+  CCScene* scene = CCScene::create();
+  CCLayer* frontend = FrontEnd::create();

[noelallen1, 2013/02/12 23:35:52]

Are you instantiating something then throwing it away?

+  scene->addChild(frontend);
+  return scene;

Is a Layer a collection of Scenes or a Scene a collection of layers?

You are adding FrontEnd a Layer to the scene.
