how to add toolbar?

Why do you ask since you have already used createMenuBar()?
read this.
http://docs.oracle.com/javase/tutorial/uiswing/components/toolbar.html

Why do you want to make your gui using functions that return components. Can't think of any reason.

I like the style of using factory methods that build and return a menu bar or other complex components. Nothing wrong with it at all IMHO. It certainly makes the code easier to read and understand.
