Meh, personally I don't see the learning curve as that steep.
But then again, I have a background in coding.. and am interested in technology in general. Where there is a will, there is a way, so to speak.
As for the wiimote / RC car.
By the time you've learned how to accomplish this, you will have found much more interesting things ;D
Like throwing out the wiimote part of the project, aswell as the RC part. Fully autonomous GPS guided car, anyone?
