Too much stain
The problem is that you have put too many coats of stain on the wood. Also gel stain and wiping/penetrating stains should not be mixed, the wiping stain will reactivate the gel stain. But the main thing is that you put too much on with out wiping any off.
Reactivate the stain again, wipe as much of it off as you can, and ask the paint store to add a little bit of paint tint to your stain and this will darken it up so that you won't have too add so much, and thus it will dry in a few short hours. Good luck
