What's a simple way to make a remote controlled candy dispenser?

Halloween is coming up and I'd like to hand out candy without being outside.

What's a simple way to hand out a small candy bar to someone with the push of a button, without being there in person?

Make a candy gun, then attach a string to your letterbox. Every time someone knocks on the door, pull the string and fire the gun.

If you just put a dispenser outside wont they just either break it to get the candy or just run off with the candy and your electronics?
