I know it's limited by the user's willpower and imagination, but is there anything the rings truly can't create?

4No, they can make those. Hal Jordan did it in Green Lantern vol. 3 issue 106. Kyle used it to kind of (unsuccessfully) restart the Corps.– Splitting AdamCommented Jun 30, 2015 at 13:49

4@cde Actually, John Stewart pulled off non-green constructs by creating them while flying at near-light speed, causing a color shift. Ridiculous physics, I suppose, but cannon at one time.– Politank-ZCommented Jun 30, 2015 at 14:12

As far as physical constructs go, it would appear that the ring is limited only by the wielder's imagination and willpower. The one exception to this would appear to be life. A Green Lantern can create something closely approximating a living being (as seen in Green Lantern Vol. 3 #48), but actual life is beyond the ability of a ring to create. It should be noted, however, that Hal Jordan thought the Central Battery on Oa contained enough power to do so:
That being said, the Green Lantern ring is capable of creating anything from microscopic nanites to entire planets. Even the color of said constructs is not limited to green. In one case (Green Lantern: Ganthet's Tale), Hal Jordan was able to shift the color of his ring's construct to yellow:
Green Lanterns have also been able to create semi-permanent constructs that last long after they leave, as well as influence life on a genetic level (both seen during the Rann-Thanagar War). And, of course, any Green Lantern with the sufficient knowledge can create additional Green Lantern rings as needed, although this is rarely done.

didn't Hal recreate his home city at one point? I don't remember if these people were just a simulation or actually "alive" Commented Jun 30, 2015 at 16:46

@Petersaber they weren't actually alive, but close. His inability to do so for real was what prompted him to head for Oa - he intended to ask the Guardians for more power so that he could make the city & people real. Obviously, they refused. Commented Jun 30, 2015 at 16:57
