John,

You can do it from scratch with PlotVectorField from the 
Graphics`PlotField` package, but you make make your life easier (and get 
prettier plots) by using my DEGraphics package, which can be found at 
MathSource (it's part of the "DiffEqs" suite of packages) or here:

Thanks for giving me the opportunity to make this shameless plug :^)
