Can you help me get to Birmingham NEC from Wolverhampton?

There's a concert in the Birmingham NEC, and I live near Wolverhampton. Thing is, I don't have the first idea how to get to the Birmingham NEC from Wolverhampton, so I'm looking for an idiot-proof guide.
If you can give exact train numbers (it's a Sunday, need to be at the NEC for 1:00PM), even better.

how far is Birmingham NEC from New Street Station?

Hi I am planning to visit Birmingham tomorrow from london. My coach will drop me at Birmingham NEC and I have to reach New Street Station. I don't know how far they are. I have to take a bus from there to reach to my destination which also will take almost 40 mins. Thanks.
