The Delhi Transport Corporation has its own home page where it lists the schedule for different bus routes (dead link) in a downloadable Excel spreadsheet. (Different routes are listed in different "sheets" within the spreadsheet so switch using the tabs at the bottom.) There's a second spreadsheet for fare stages that lists all stops on a particular route (you need to switch to the "Fare Stage" tab). Perhaps not the most intuitive way but at least you have the information in some form. Usually, people at bus stops will be happy to help you out with information on what bus route to take (if they speak English, that is).
Another pertinent point is that given Delhi's traffic, it's highly unlikely that the bus schedule will be helpful. YMMV, don't expect the buses to turn up or reach their destination on time.
