Greenguru,
You've got one that I have never tried making. About eight years into the hobby, I've tried many fruits with varied success. Luckily, I've got a friend in the food business who gives me fruit (when it "exceeds profitability" in the stores - aka going bad) and I make wine with it. A cool combination that costs me only time, sugars and yeast. As a recent addition to this forum, I ask have you ever done banana or tomato? Both sound a bit horrible, but they do have a great flavor when they come out right. I don't use sulfates, so I let the yeast terminate from the alcohol content which of course yields very potent product. The tomato with high acidity actually finishes akin to a citrus. Most folks I offer it to are reserved when I say it's tomato wine, but if I share it without them knowing what it is, they are usually pleased, can't quite make out the flavor (a lot believe it is a kiwi or other similar fruit.) As odd as it sounds, it is good. I've got 15 gallons going currently. I will let one batch go dry and back sweeten the other two before bottling.
I entered a local home-brewers competition a few years back with the banana wine and ended #10 of 19 (I was the only wine dude amongst beer brewers.) If you care to see here is the link

I applaud your efforts and I think I might attempt pumpkin myself. Any tips on the process would be appreciated.
