The Zeus statue doesn't exist anymore. I don't know exactly what happened to her, but with the Olympics this year displaying many of the ancient traditions I think it's likely they came up with something that looked like it.
As NewOrder pointed out already the Pyramids and the Lighthouse of Alexandria were Egyptian and the hanging gardens of Babylon well babylonian. As for the The temple of Artemis in Ephesos and The mausoleum of Halikarnos in Karien they were both located in what is today Turkey but was sort of a Greek colony back then. Artemis is a greek goodess, but I'm not absolutely sure if Halikarnos was a greek or an Asian ruler (I have to look it up). However in spite of the fact that the Greek people considered themselves sort of "above" the other people calling the others "barbarians" which means "stutterers" (a word that was adobted for anybody who shows no sense for culture, art and the like), Greece was far from being one united country back then. People from Athen, Sparta and the other Greek "polis" (this word means town and you'll still find it in some town's names today, e.g. Minneapolis) fought fierce wars against each other. So it is not an indisputable image of Greek being one nation responsible for all that wonders. Rhode Island for example was more attached to the island of Kreta (which under their Minoan rulers was more like an independent nation than most of Greek was). I have to admit I don't know just how strong the Greek influence was by the time the collossus was built.
