Dryer cross-wired - loud pop and no longer works?
Are you sure you didn't trip the breaker or at least one side of it. Try turning the breaker all the way off. Make sure both poles are pushed to the off position. Then turn it all the way on. If you have a voltmeter then check to see if there is power on both poles of the breaker. It should read a nominal 240V.

If that isn't it, then try and locate the POP sound by seeing if there is a faint smell of smoke from the receptacle or the dryer. If it is the dryer, then chances are you have burnt up some of the wiring in the dryer and if that is the case odds are you are looking at getting a repairman on the dryer or buying a new one. 

I say this because you have said you are not all that handy and tearing into a dryer to make a DIY repair requires a certain amount of mechanical expertise.

Good luck and sorry for the bad news.
