I highly doubt there is such thing as "BBG layout tutorial", these are generally done identical to "normal" layouts. The only thing that you could keep in mind is that it will be "stretched" verically more (althrough some make it fixed height), you might also need dynamic menu (variable number of options) and the most important, the number of options on the menu will almost surely change duriong the game life cycle so don't make it as static gfx (unless you have very strict design habits and won't change it later once decided upon intially).
More interesting would be reading about game interfaces, but this falls more into game design theory than layouts and gfx. I can not recall any good article about it either right now.
