I guess this is a polymorphism question. In the Notebook class I am wanting to call the setFont method from the Page class. I can create a Page object but that object is only viable within the method I create it. Then in the Page class I am wanting to get the font of the text area that's created in the Notebook class.

google gave me this:

what's wrong with page1 you declared at the top?

also I don't really think you need extend Page with Notebook. You Already have an object page1; you should be able to access all of Page -s methods with that.
so you could use:

I dunno, haven't tested it or anything, but the object is there and methods are public, so I can't see why it wouldn't work.
