I need a code and wiring diagram for two servos

I am working on a costume piece and have reached the stage where I need the servos to work with the push of a button. I wish to be able to move the servos from point A to B with the push of a button, then from point B to A when the button is pushed again. And if possible, another task/mode where the servos move in opposite directions of each other when the button is pressed. Hope to hear from you soon. Thanks.
