The best way to learn is by example. The beauty of Rapid-Q is its simplicity.
Look at this code to make a 'hello window' window application.

'text behind a comma is treated as a comment
'make a form called Form
CREATE Form AS QFORM
     Caption = "Hello World"
     Width = 640  'set its size
     Height = 480
END CREATE

'now we run the application
Form.ShowModal

I tried that and it works.

Maybe it is a semi-dead software, but seems to work to some extent, I don't know anything about it myself.

But seems to be somewhat like very old basic, maybe also like GW Basic, QBasic-QuickBasic and maybe Visual basic.
