Mapping Wiimote to a controller?

I don't like the wiimote at all, but some games require it.
For example Skyward Sword needs it for attacks.

Is there a way to map wiimote motions to a controller analog stick or button?
In Skyward Sword for example I'd like to be able to attack with a button like in older Zelda games.

If not by only using Dolphin, is it possible to achieve this with joy to key?

Thanks in advance.
