If you are developing several applications for bitcoin I highly recommend you learn the bitcoind API. It does a lot and works really well. Why would you want to avoid having a local server? If you post here you will get help very fast.
I will even get you started with this script that sends money in Python:
from jsonrpc import ServiceProxy
amount = 0.5050
sendToAddress = "1putanaddressheretosendto"
access = ServiceProxy("http://username:password@127.0.0.1:8332")
balance = access.getinfo()["balance"]
print "BALANCE: " + str(balance)
transaction_id = access.sendtoaddress(sendToAddress, amount)
print "TRANSACTION ID: " + transaction_id
How easy is that? Super easy!
