Yes, no (or, rather, "only partially"), and maybe.
Pepsi has recently (Dec 2009) released something called "Mountain Dew Throwback" which is made with sucrose only rather than "high fructose corn sweetener." Sucrose is what most people mean when they say "real sugar."
Regular Mountain Dew is made at least partially with high fructose corn sweetener, which is a mixture of fructose and glucose.
However, fructose and glucose are both "sugars" in a chemistry sense, so even that is technically made with sugar... just not table sugar (cane sugar/beet sugar), which is sucrose.

Fans of Mountain Dew
Mountain Dew is essentially sugar. It is a fertilizer for the plants.
Diet Mountain Dew has a sugar substitute while regular Mountain Dew uses high fructose corn syrup.
Many computer programmers drink Mountain Dew for the sugar rush and caffeine.
Dr. Pepper for the record has the most caffeine even more than Mtn Dew!!!
mountain dew is not made on a mountain because it is an ordanary drink that can be made in an ordanary factory like the rest of the drinks in the world.
Mountain Dew has a strong dose of both caffeine and sugar.
