The only way I am with you on avoiding IC's is if you are exceeding 25V. and even that, I wouldn't even make a circuit because anything over 12V IMO is ridiculous with the exception of turning on large motors.i want to avoid using IC's
So when do you want the 2 second timer to start, when you release the button, or as soon as you touch the button, or only while the button is pushed? Your answer to this question will determine some of the IC's to use.I want to make a circuit with 6 led's, when a button is pressed it will randomly choose one led to turn on.
the led needs to stay lit for 2 seconds then turn off.

As for truly random, I doubt you will get an answer, but you can do some sort of randomness as follows.
When the button is pressed, a 4017 counter is continuously going through all 6 LED's until a clock feeding the counter stops. If the clock is at the right frequency, you just might get a random number each time.
