I love making wine, been doing it for years before I got into brewing. My suggestion is work with a couple of the kits first to wrap your head around the process.
If you really like the sweet berry I would go with the WinExpert Pom Zinf kit. It's cheap, easy to make, and will be ready for those summer patio drinking days.
Once you've got a few kits under your belt then go for making wine from berries/fruits. Once you do you'll really want to spend a few days reading Jack Keller's Wine Blog. http://winemaking.jackkeller.net/
I make my yearly run to the pick-your-own farms for strawberries, blackberries, cherries and blueberries. Each of those make fabulous wines. Just remember one thing: If you think brewing beer takes patience wine requires that level 10 fold. Those berry wines don't become drinkable until about 1 year, and really come in to their own around 2-3 years.
