Short of making a second batch without the wine in order to dilute it (which in most cases is a dumb and impractical suggestion), there just isn't much of anything that can be done. Sweet, salty and sour are very tough mistakes to mask or fix. The expense is chalked up to experience.
It also helps to have a backup handy, such as frozen boneless chicken breasts that can be thawed and cooked in just a few minutes.
