Miss kitty doesn't want to share her home with her new adopted sister. She seeks out the nearest piece of furniture near Gwen, hides under it, and growls at the dog. She occasionally pops out to hiss and swat. Then the dog thinks the kitty is playing and starts jumping around and barking.
I know only time will help, but is there anythingI can do to help introduce them in a more healthy way to get them use to each other?
Kitties don't like changes. It takes them a while to get used to them. I would make sure that Miss Kitty always has a safe place to escape to (a bedroom closed off by a baby gate, for instance). Also, crating Gwen, and allowing Miss Kitty to check her out that way should help. But, as you already know, all supervision must be supervised for now, while these two decide how they are going to live together. They may end up best buddies, or they may decide to mutually ignore each other, or it may be something in between... only they can decide.

When I brought home my first Boxer, Smokey was furious. She was indignant. She was being a typical kitty.
Smokey was a 16lb Maine Coon, so she did have some weight behind her anger. I had to be careful. Originally she was stalking the puppy so I would keep my eye on them. But quickly that puppy grew up and up and up. The wind changed a bit as Smokey had to crane her neck to look up at the puppy.
The showdown came when the puppy was running in circles around Smokey and barking up a storm. Playful barking of course. Smokey had figured out by now this was some sort of a baby. She waited until the puppy got a wee bit to close. She then smacked the pup about 3-4 times on the muzzle; lightening fast. The pup screamed and ran. I caught the puppy to investigate the damage. One thing scratch on the nose. Considering the cat never advanced on the puppy, I figured this was the only way the puppy was going to learn to give kitty her space.
And it worked.
Smokey raised 3 adult Boxers during her life with me. She was buddies with them all and even enjoyed using their dog beds. She lived openly with them and they really did love her. Smokey got Boxer kisses often, though of course she seemed annoyed at having her facial fur ruffled.
It all just took time to the make the adjustments. As Susan said, Kitties really don't like change.

Now Gwen wants to chase the cats. They have a section of the house to themselves that they hide in but come out sometimes to investigate. Gwen goes crazy looking for them sometimes. *sigh* I'm starting to worry that they won't get any better, at least be able to tolerate each other. How do I correct Gwen so she understands the kitties are off limits?
Tell her NO and then encourage her with a toy instead. Reward her for staving off her kitty chasing. In the end, they will all have to simply figure it out for themselves.
