I don't think so. Practice standing more. On a slightly uphill bit of road, put the bike in a big gear so that you're pedaling slowly, then stand for a while. Work on getting your upper body motion correct so that the front wheel doesn't wobble back and forth. Rock the bike only slightly and notice how the timing of your rocking has to coincide properly with your pedal downstroke to get the motion correct and easy. Try to ride on the fog line. I find it helps to keep my knee close to the top tube when the pedal on that side is near the top of the stroke.

Another thing you can play with while the bike is in that big gear: pedal seated while trying to put force on the pedals all the way around the circle, so that your upper body is completely still and again the front wheel doesn't wobble. Then try to transfer that feeling to the standing position.
