Learning Japanese with Eclipse RCP applications

I'm not good in any language not even my mother language but I want to learn Japanese.Yes you guessed I like those cartoons. There is a great application to learn Chinese called ZDT. The ZDT (Zhongwen Development Tool) is an easy to use, open-source Mandarin Chinese flashcard application that can help you learn Chinese. It is written in Java using the Eclipse RCP platform.
I don't have interest on the Zhongngwn language, I want to learn Japanese! Do you want to help me to add a Japanese database to this great tool? may be for the project? Let a comment!

Azureus/Vuze

Azureus, Probably, the first application using Eclipse technology I have used. And one of the most popular ones. Is a Bittorrent open source client. Full of great features, for advanced P2P users that need to know every detail about the transfers, peers, performance, network status. Many plug-ins are available making it more interesting and powerful than other p2p clients. I thought it was based on the Eclipse Rich Client Platform, but it doesn't seem to be the case, looking at the source the plug-in system is not OSGi. It seems they only use SWT but not the RCP framework
