Topic: Getting a Balance Using Bitcoin Web Service? (Read 1369 times)
Not sure about easy but you need to:
1) locate the most recent transaction involving the address.
2) the number of coins transfered to it is the current balance (barring any unconfirmed transactions)
3) if the address is not in the block chain then it has a value of 0.

I want to develop a bitcoin app on Google App Engine (GAE). However, I don't know if I can actually run bitcoin on GAE. What I need is to be able to get total balance given a bitcoin address. What is the easiest way to do this? Thanks.
