Okay! I see what you mean now.
In that case, you just need a Japanese-English dictionary! There are two different types:
One type is where you look up the words using romaji. Here
is one example of a good one. So to look up ringo you'd just go to R and find ringo.
There are also ones where you look up the word using hiragana (and katakana where necessary). Here
is an example of one that is really good for beginners/intermediate learners. So in this case, you'd look up りんご、there's no romaji in this one. Please be aware though that the words are in order of the hiragana chart - it helps to really know that order before using a dictionary like this. If you get used to it, though, I think this kiind of dictionary has its advantages over a romaji one!
Hope that helped
