Not quite sure if this is what you want, but here's a simple fluid file
that might get you started...
Save this a something.fl, then generate the .cxx/.h files with
fluid -c something.fl
Then build the test with fltk-config
fltk-config --compile something.cxx

# data file for the Fltk User Interface Designer (fluid)
