water tank controller

dear all,
i wanna highlight that this is my first time with arduino and I'm not understanding what you saying. I'M STILL LEARNING...
after that, what I wanna do is very easy.
when I press the button named PULS1 the power on relay ''RELE2'' will be off until when I press again the same button, but at the same time regardless of the button (PULS1) if the button ''GALLEG3'' is excited the power on the relay ''RELE2'' will be immediately off until I takeoff my finger from the button.
can some one help me?
pleeeaseee
