How can a console command executed from a program create a graphical dialog to respond to an input prompt?

Question

How can a Lazarus/FPC program that is executing a command via TProcess detect an input prompt and create a graphical dialog for the input?

e.g. say I execute an ssh command via TProcess which requires a password to be input - how could it detect it, prompt for it with a graphical dialog and pass it on for the command to continue?

2. For X-Window graphical screen you can use zenity and grab the output, it'll contain pure text password, example: zenity --password --title "Security question: "
