Hi, I registered just now, in order to post. I was also searching all over for a Dutch dictionary, or a way to create one.
I found step-by-step, easy to follow instructions here:

This guy explained it really well, and the dictionary that you download from Babylon is a legal download, and free to use.
The only hiccup I experienced, is that the html file generated from the Babylon file (once you read his instructions this will make sense) came out with something like "00003A" in the place where the ":" should be, but I just opened the html file in a text editor and did a replace all of the string "00003A" by ":" and it all worked!
For instance, where the html should read "idx:entry", it read, instead "idx00003Aentry" (or something like that) and that's what I fixed with the search and replace all.
Good luck!
