Wallet Internationalization - Bitcoin QT already has the ability, but as I've changed some things not everything is internationalized. Someone needs to go through it and make it fully internationalized. There is a web service that can make it easy, transifex.com
That seems easy enough... I'll take a look.To translators: All you have to do is go to the link, click "Help Translate 'ShinyCoin'", make a username. I'll approve you, then you can get cracking. I'll update my git branch periodically ( https://github.com/csaftoiu/shinycoin/commits/i18n ), and make pull requests to the main repo when there's a good amount of translations done. Or sunnyprince, you can pull the files yourself also (merge my changes, then use "tx pull -a" to pull new translations).
EDIT: Can test existing translations with the -lang flag, e.g.
./shinycoin-qt -lang=zh_CN
