The main thing to keep in mind that the main program loop in a GUI
program is to handle all the (internal) GUI stuff, not your console
program loop. A RAD tool like Lazarus, will conveniently handle that for
And you can't just pop up a dialog window without having a window/form
in the first place.
In general, the logic of a GUI based program (regardless if Windows,
macOS, Linux, etc) simply is different from a console program. Your
console program main loop simply pretty much just becomes a procedure
within the GUI main loop.
