Litecoin/Bitcoin wallet with push mechanism?

[chickun.arise]

I would like to know if there is any way I could recieve notification when new tranasaction occurs? My project is: I have to instantly check if a new transaction in my wallet happend and if it did I have some database queries to execute (in c++ or any language) How could I recieve this onTransaction notification? I was playing with node.js client for litecoin but with it I can just constantly pull request on new transaction and this is not efficent. Any suggestions, experiecne will be appreciated. Thanks
