KiCad is quite capable. It's used in the qi-hardware group
where Werner Almsberger has added a nice footprint editor.

Lua is a good language. I don't think you'll go wrong
with C however. The entire Arduino universe is
a pretty good existence proof that C is palatable. We;ll,
they have some libraries that make things easier.

As to your approach to measure wind speed, it is a clever
idea, but the old fashioned way is pretty easy.
