You can file the motion and hold your breath - but - if the plea was the result of a plea bargain, essentially YOU agreed to the plea. How can you appeal your OWN self-bargained plea.
I don't think you can appeal after a guilty plea.

Appeal
Usually, as part of the plea agreement, a person who pleads guilty waives their right to an appeal. There can be exceptions (e.g.: if you were represented by an attorney, you could plead inadequate counsel), but only an attorney could tell you for sure.
It saves the government plenty of money. Defendants who are represented by private counsel can save a bundle on attorneys' fees by accepting a plea bargain.
If you've already accepted a plea and have been pronounced guilty you would have to actually file an appeal to the next higher level of court before any release on an "appeal bond" could be considered.
The answer is no. I took a plea deal on a bad case and the police officer was discharged for lying on his case files. I was not allowed to have a new hearing due to accepting plea deal.
I've been trying since 2005 to appeal a plea with a habeas corpus appeal due to new evidence we didn't have at the time of the plea, and since I agreed to take an Alford Kennedy plea but somehow that got lost in the paperwork somewhere. This is now 2012 and it's still pending, so I have no idea as yet if it will even work as they won't give me an answer. This is in West Virginia.
A siren song is a plea or appeal. This is generally very enticing, but it can be deceptive in nature.
If you pled 'no contest' (which is effectively a 'guilty' plea) and the plea was accepted and you received judgement, it is pretty much too late to reverse your plea now. You could try submitting a motion to the court for a request to consider withdrawing your original plea, but it might be too late, and the only course of action open to you now would be to file an appeal with the Court of Appeals.
An inmate who pleaded guilty might prevail on appeal if he could show ineffective assistance of counsel or some misrepresentation of the consequences of his plea, but this would be unusual.
