SQL to MDX translation?

An MDX (a language dealing with multidimensional data, in particularly dealing with the cube metaphor) statement can be translated to an SQL (a well-known language for the relational model) statement - Mondrian is one example solution which provides such translation. I was wondering if there are any available solutions to provide a translation in the other direction, i.e. from SQL to MDX. If not, what would be involved in creating such a functionality?
