Is there a bus from Wuhan to Hangzhou or Jingzhou to Hangzhou?

Yes, you can take a direct bus to Hangzhou from Hongji Bus Station. The bus departs at 14:00, and the fare is CNY 284. The trip takes about 12 hours. Or, you can take a bullet train from Hankou Railway Station (about 5 hours).

As I know, you can take a direct bus to Hangzhou from Jingzhou Shashi Bus Station. I heard that the bus departs at 13:00, and the trip takes about 13 to 14 hours. Or, you can take a bullet train (about 7 hours).
