A glove that is windproof, waterproof, warm down to negative degrees, and provides finger dexterity pretty much doesn't exist. You'll get one or two, but not all of those features.

If you want windproof gloves to near zero, then one of the softshell gloves by Gore would fit the bill. But they are not waterproof, it may only be a DWR coating.

If you want waterproof, where ZERO water get's in, then you will lose finger dexterity because of the layers and membranes inside the glove.

I currently have the Gore Countdown gloves. Windproof, completely waterproof, but finger dexterity is an issue. Doesn't mean that I can't shift gears, but it means that sometimes I'm fumbling around. I've gone through 4 hours of heavy downpour and hands were completely dry. Good for commuting through winter.

Gore has a newer one called GTX-1 for road cycling. It's thinner than the Countdown, but is waterproof and wind resistant. Finger dexterity is good. Downfall, i don't think it would be suitable for negative degrees because it's a bit thinner. You will need to wear a liner on the inside.
