Hello there,
well i have several softwares to helping you with that so i will post you some very usefull software, but i just have the name,

But i think it's easy to find it on Google,
so no problem.
So here are the softwares:
JquickTrans
A very usefull software used in university's to translate Kanji's and Kana's.
Rikaichan
An Add-on for Firefox to read kanji's on websites in Japanese (very usefull !!)
Moji
Another Add-on for firefox who use the same interface of Rikaichan, but it's more powerfull i think and way more detailled.
I still have some softwares,

but anyway these softwares will help you a lot !
