Hi ryangodammit,
Yes it has been done, but I can't find an appropriate link for you. :(
Here is a very basic example I used for testing purposes.
Code:
--------------------
#!/bin/sh
# Play/stop Squeezelite
# Push button connected to GPIO17
player=started
echo "17" > /sys/class/gpio/export
echo "in" > /sys/class/gpio/gpio17/direction
while true
do
PRESSED=$(cat /sys/class/gpio/gpio17/value)
echo $PRESSED
sleep 1
if [ $PRESSED = 0 ]; then
if [ $player = stopped ]; then
echo "Start player"
echo "play" | telnet 192.168.1.101:9090
player=started
sleep 3
else
echo "Stop player"
echo "stop" | telnet 192.168.1.101:9090
player=stopped
sleep 3
fi
fi
done
echo "17" > /sys/class/gpio/unexport
exit
--------------------
Then there are decisions to make about:
- polling or interrupts
- shell script or python
- use wiringPi or not
Here are some "out" examples, that might give you a few more ideas.

The "Audiophonics-powerscript.tcz" extension has a script.
