Haskell coding environment for windows users?

Hi, I am not sure whether this is the right place to ask this question. I want to know what's the Haskell coding environment used by GHC users on windows? What 's the preferred editor? Is there any Haskell tags for vim? Also, is there any program which will convert Haskell modules to HTML with cross-links so that one can use the HTML files to browse the source? Please let me know. Thanks. Bye. - Srineet.
