I have to agree with Dean's sentiment.
The " Four" Galilion Moons of Jupiter are only very small subtending only arc seconds. so it is very doubtful you would see any of them.
It has been said that some African tribes saw the moons in the past,but with the contrast of the sky and the closeness of the moons to Jupiter it is highly unlikely.
As you know when you look at bright objects your eyes can sometimes fool you into seeing double objects,"Alpha Centurii for instance.
