The amount of effort of these points depends on the configuration of your operating system. If you'd like to keep it fairly light weight, you can try fpgui or mseide+msegui, which talk directly to the X server (assuming you have an X server running, otherwise you'll have to talk to the frame buffer or use sdl). Lazarus targets the heavier widgetsets, but I've seen posts about using it with embedded Qt, which may suit you well. I also don't know if anyone has tried the gtk framebuffer port, which also looks interesting. I can at least confirm that I've managed to cross compile and demo fpgui on an embedded linux system with an lcd.
