I've done this in the past with some stuff that hasn't been released. And that is to open a graphics window be it tiny ptc or fb gfx, and using the area or regions of your rectangles based on the position of images used for your required option.
And then check wever the mouse is over one and if a clicks been made the selection changes for that particular options variable.
When start has been clicked on that then takes you to the main event, obviously you'd need to close the gfx window session for the options and make a new one, you probably could resize it in fbgfx.
hope that helps and makes sense,
Clyde.
