use of Gui bitmap buttons in the gui editor in 1.5

can somneone please walk me through placing a gui bitmap button on the gui and making it work in iTGB 1.5? every tutorial seems to assume that I want to place a button on the actual scenewindow but my issue is I am working on a scrolling platformer using the platformer starter kit. So I need my buttons to stay on the screen at all time.. One would assume thats what the gui editor is for but for the life of me I can not make a single guibitmap button to work. All i need is a small walk through on getting a single button working in the gui editor and I can manage the rest.
