You shouldn't need to use anything so crass as pointers to accomplish
this.  Try taking a look at the Map data structure in Data.Map:

  http://hackage.haskell.org/packages/archive/containers/0.2.0.1/doc/html/Data-Map.html

If there is some reason Data.Map won't work for you, please explain
why so we can better understand what you are trying to do.
