There are special little gadgets you can get to melt chocolate for baking and candy making. I'm no expert, but my wife uses one for melting different kinds of chocolate and drizzling it all over stuff for the holidays. It's like a little electric pot that warms the chocolate up until it's all melty.
I can tell you that pretty much anything is good with melted white chocolate on it. Cookies. Pretzels. Old boots.
Not sure what it's called but a quick google search turned up a bunch of such gadgets. Seems way easier than trying to do it on the stove or in the microwave.
