Printer port pins, serial port status pins, mousebuttons from an old mouse connected to serial or mouse port...... Well,those together are good for about 9 input pins,more if you use the printer port bi-directional.
Can you more fully describe what you want to do? The answer is yes, lot's of ways, but I'd like to see a better description so the answer would be a better match to what you want.
wired (joystick port, serial port, parallel port, usb) wireless: (irda, bluetooth, wi-fi)
probably, eg: you could use the switch to power the device and just ping it from the computer to see if it's on.

I think home automation. The computer can control relays and do more spesific realization of the command, but I'd like to be able to give this commands from anywhere from the house.
The idea, that there is some device and switch turn the power on it and the computer pings, if it is on, is possible. What are the simplest, smallest and cheapest devices to use for that? The signal should go througth the brick walls.
Why use so much costly PC to switch on domestic devices? There are so many devices available which use Ur TV/DVD/Audio systems' remote and some are capable to regulate fan speeds also. They can be used in any room with installing IR detectors where required.
But think of consequences if U switch off water heater accidently when somebody is taking bath !!!
Try Google for *X10* or check

Google "wireless remote control" (no quotes)
I think that domestic instantaneous gas "hot water on demand"
heaters use water pressure switches to turn them on and off, so it's
not likely that an RF or IR signal is going to turn them off.
Storage water heaters, like we have here in most of the US, are
wired directly to the mains through circuit breakers, so it's also
not likely that IR or RF will turn them off. Even if it were to
happen, though, it wouldn't make any difference since the remainder
of the hot water in the tank would continue flowing out, resulting
in pretty much a normal shower.
