I'm not sure if the wget maintainers would be interested, but I've been carrying this patch around in my private builds of wget for a while. It allows wget to load SSL certs from the default Windows cert store.
The patch itself is fairly straightforward, but as it changes the default SSL behavior, and no care was taken to follow coding convents when I wrote it, so it's probably not ready for inclusion in the codebase. Still, if it's useful, feel free to use it for ideas.
