In my 2nd year of university my group built built an osciloscope with a GUI written in Lazarus and the hardware being an ISA Board . For my project the following technique was more then enough: http://wiki.lazarus.freepascal.org/Developing_with_Graphics#Create_a_custom_control_which_draws_itself But as others have pointer, there are other solutions.
