Cornmeal is less than 1% simple sugars, as is cornflour. While it's not great compared to high fiber low gi sources like brown rice or sweet potato, it's not sugary at all. You have to split the polysachharides somehow to make it into sugar. Of course if you spend extra time, money and energy turning your relatively ordinarily healthy grain (which is admittedly a low bar) into sugar you spend more time, money and energy and wind up with sugar. It's no different from wheat in that regard other than you should maybe add a bit more fiber to the meal.
