  • How is the pc connected to the raspberry pi? (Serial, Ethernet/WLAN, etc) – HectorLector Feb 12 '14 at 12:25

To detect a button in GPIO, try the https://projects.drogon.net/raspberry-pi/wiringpi/the-gpio-utility/.

With a bash script you can use this tool to detect and send a signal to PC.

Now the second part, how the two will be connected? If LAN, you could use a simple webserver in your pi, with some push server or node js to run your script and show the result in the PC browser.
