Raspberry traffic light by working solution

Good morning. Someone gives me a hand.
I have 3 LEDs to make a traffic light with a Raspberry Pi 3.

If someone has made a small application that can turn on each light when I need it.

I have seen several examples, but it does not show very well the wiring of the LEDs in the electronics of the PI 3B.

I would appreciate your help someone wants to take this small project, give me a price $ Pay by PayPal

Thanks.

Are 4 pins 3 and 5v ground.

I don't have any idea about coding, I need a working example for a Raspberry PI3
thanks.
