You can draw the background image for the application first and then draw the transparent pictures on top.
I've attached a simple program that demonstrates this method. A circle moves back and forth across the screen. Three transparent buttons are in the upperleft corner. Press 'ESC' to quit the program.
With this method, you need to redraw the transparent objects for each screen but it should hopefully provide the desired effect.
