There's nothing in my O'Reilly reference about this. If I was really keen on doing that, I would either create my own pop-up that mimicked a confirm box or I would change my question around so that hitting 'OK' was the way to back out of submitting.
For example, instead of: "Is this information correct? Press 'OK' to continue. Press 'Cancel' to edit your values", you could write: "Would you like to edit these values? Press 'OK' to return to the form. Press 'Cancel' to continue."
The second idea is much less-convincing to a user, however. The first method requires a little programming to get it to work just right (but it DOES allow you to label your buttons the way you want).
Obviously, the third alternative is to let the fat-fingered user beware. Are the results that dramatic if they accidentally hit 'OK' when they meant to hit 'Cancel'?
Perhaps you could add a SECOND confirm box with an "Are you sure?"-style question as a just-in-case measure.
