Robert and others

First, I admit that I have no idea how to write a code for pic's. this is
the reason I ask for help.
What I am looking for is very simple, a circuit that start when a switch is
pressed for a brief time I call it "start".
this switch is ignored if pressed again until "reset" switch is activate.
another switch is activating a led while is pressed alternately this I call
it  "running".
the "reset" switch function in this way: if the switch is pressed for lets
say 10 seconds (no less) then a buzzer is activate. any time less then 10
sec will keep the circuit running (led is blinking while "running" is
alternately pressed) and "start" switch is ignored.
if "reset" is activated more than 10 sec then "start" switch can start the
circuit all over again, and so on. like a loop.

hope I explain my self coherently.

I'll appreciate any help!

Tal

Sounds more like a homework assignment.

Not enough detail. Monitor for days, hours, minutes, miliseconds?
