flashing lleds

Hi all I am just starting my first my first project which is making 4 led flash in a timed sequence .
What I would like to do is push a button to start the sequence then 1st amber led comes on for 1 sec . then after 1 sec 2nd amber led comes on for 1 sec then after 1 sec 3rd amber led comes on for 1 sec and after 1 sec 4th amber led comes on for 1 sec only then no leds are left on

Thanks for any help in programming and wiring
