See Matt's detailed reply, but along with that, I *very strongly* suggest you spend some time playing around with fltk on your desktop system, get a proper feel for how the widgets behave and experiment with the handle() methods and how the events are propagated. It is a lot easier to do these tests on the desktop system, and so much easier to debug and to understand where things are going awry. Then, once you have that and can make a demo prototype of the GUI you plan to put on your embedded target, it will be much easier to create the code for the real system, and the design you cerate at that stage will be more robust and correct as it will benefit from the experience gained whilst doing the desktop testing.
