Swing GUI help

hey i'am using a swing gui, so i have two questions:

first, in my app the gui don't appear, i don't now how, i think is because my game is a SimplePassGame.

How can i show the gui in a simplepassgame?

second, can i change the layout of swing gui? for example, put a image to be a Hit Points Bar for example?

or you recommend me to use another gui

PS: i'am using NetBeans
