Logic gate help Answered

I'm attempting to build an binary calculator out of an old iphone box using LED's and such and have a wiring system set up but i need to know how to make/buy some form of "if then else" gate (i.e. if A=1 then B=1 else C=1 and if A=0 then B=0 and C=1). I would love to know if there is some kind of way to do this using transistor logic but anything that works as an "if then else" gate is welcome.

an idea (smple) is to make a table using leds (red=false) (green=true)like rgb leds....and then using microswitches you can have the apropriate result.
