Best quick guess is that your master cylinder is gunky and the return hole plugged.
GL1100. Front brake sounds while turning
I have an '83 GL1100 standard.
So I started to notice that the front breaks will make a slight rubbing sound when turning at low speeds. I am not sure why through... I tried to move the front wheel with the bike on the center stand but it wont budge with my hands. Calipers seem to be firmly in place as well.
Any ideas why this would happen? Do the pads flop around in there?

The pistons in the calipers have most likely seized up from the winter lay up.
Just to clarify, when you say the wheel wouldn't budge ant the caliper seems to be firmly in place, do you mean the wheel wouldn't rotate because the brake is holding it, or that there wasn't play in the forks or steering head and the caliper wasn't loose on its mount?I have an '83 GL1100 standard.

Sorry I worded that really badly.
The wheel does spin. When I said won't budge I meant when I try to push it side to side, which I think is how you check for a wheel bearing.
So the caliper is releasing ( which actually was a problem a I fixed few months ago )

Pretty likely the noise is from the speedometer, cable or drive gear.
The pads do remain in contact with the disc for the most part when not applied so it's not unusual for some slight noise to come from them. If you have the front wheel jacked up and the wheel will spin odds are that's the problem
If there's any significant drag on the wheel it's usually either the small port on the banjo bolt end of the master cylinder. It looks like a dead ended hole in the bottom of the reservoir when you take the lid off and the diaphragm or float out of the reservoir. It's usually covered by a little aluminum cover in the bottom of the reservoir. That cover will pop off easily. I usually use a whisker from a wire wheel held in a small vise grip to poke out the little hole in the bottom of the larger one. You don't want to increase the size of that hole though.
The other possibility is a stuck caliper. Look at your brake pads, if one is a lot thinner than the other the caliper is most likely stuck. That takes removing the caliper and removing the sleeve through the caliper where the smaller mounting bolt passes through.
Both a plugged port and stuck caliper can cause brake drag and even wheel lock up. If you're just hearing a slight noise and the wheel is free it's probably not a problem, it may just be audible because the wheel is turned so the rubbing pad is aimed more toward you and because you're going slow with little power. If you can hear it when turning at speed then there's a problem.

Yep pretty bad wording LOLSorry I worded that really badly.

Sounded like you meant the brakes had the wheel locked.
What Dave said, or just pads rubbing normally maybe?
Disk brakes have no way to back off away from the rotor other than to just rub and push away during the rubbing as wheel rotates.
Of course the old drum brakes had springs to pull the shoes vack away from the drums, but disks have no such thing!
If there is allot of rubbing check that all brake caliper parts are clean and working freely. If pins get gunked up or corroded or pistons stick etc.. and the pads do not back off as they should then 1 pad will wear more than the other often.
To hear some minor rubbing at times is pretty normal though for disk brakes.
OK just did a bunch of driving and not only am I bad at wording posts but I'm also a bad listener.
I think the noise is actually from the rear and definitely only happens when I turn right. When on the center-stand the tire spins freely but does not appear to shift right or left when I push on it.
Could it be something in the diff?
