Can I make web interface for hardware events?

Also I think you didn't get the full idea that I am working on..
The keypad is wired into different circuit that is using it... I need to monitor this key pad and check which button was pressed... to get the idea please see this pseudocode to get the idea:

The keypad is implemented this way: pin1 & 2 are the driving lines; pins 10 - 12 are sensing lines
      pin 1    pin 2
        |        |
pin10--pwr------ |----
        |        |
pin11--tUp-----tDwn--
        |        |
pin12--fan-------|----
        |        |

to detect which button is clicked I have to do this way:

while(true){
      if (pin 1 == low){
        if(pin10 == low)
            pwr is clicked;
        else if(pin 11 == low)
            tUp is clicked;
        else if(pin 11 == low)
            fan is clicked;
      }
      else if (pin 2 == low){
        if(pin 11 == low)
            tDwn is clicked;
      }
}
