Accessing the acceleration meter data and gyroscope

[Breckie1]

I don't know if I am particularly dense or if learning how to program as a dyslexic was a bad idea but I want to access the angle of the controller, basically (pseudo code)
if(tilt to left)
{
do stuff
}
if (tilt to right)
{
do more stuff
}
if(tilt upwards)
{
do something else
}

if(pulled straight up)
{
jump
}

I have no idea how to access these values and I've been trying to read through the readme file but I still don't get it.
I have a Wii Motion Plus controller and a dolphin bar
