I built all the exterior doors for my house and can vouch for the feasibility of doing this in a home shop. Just a word of warning before you start -
a standard height, 36" entry door in solid oak will weigh between 125 and 150 pounds. All the pieces will have corresponding weights - an 8" stile will weigh almost 30 pounds. Running a 7' long, 30 pound board through the jointed is a lot of work. Once assembled and sitting on sawhorses, just turning it over to sand the other side is a major task. Just a heads up on what you're signing up for.
As to hinges - with a 150 pound door, ball-bearing hinges are the only choice.
Here's the front door. Port Orford cedar, so it doesn't weigh as much as oak, but still a lot to deal with:
