With great difficulty. The Fitbit API doesn't include functions to send notifications, so you'd need to do that part using some other software (eg, a native app, although there might be utilities that could do it).
You'd need to write Fitbit code to read the achievement and goal data, and pass that to your notification app.
Perhaps you could do it all in one app (possibly a web app) using the Fitbit Web API.
