Yes there are buses from DTD to all parks. I have not seen a recent travel time listing from WDW but I give 45min - 60min to get from most resorts to most parks.
Don't forget when those guests parked at DTD to get on the buses to the parks that meant less parking spaces for those wanting to visit DTD and how was that fair to them.As Jestocost said there are NO buses from DTD to any park. The reason is pretty obvious. People would overwhelm the DTD buses and parking lots since you dont have to pay to park at DTD.
