Expression builder in Javascript or jQuery?

Question

I am searching for an expression builder GUI (like the one used in Microsoft Access). It can be plain Javascript or JQuery plugin. I am loathe to build my own and reinvent the wheel if one already exists - and yet, a search on Google does not find anything remotely useful.

Is anyone aware of any such library/plugin or article that covers this?

Have you looked at this: http://plugins.jquery.com/project/SQL_QUERY_BUILDER? Its not pretty, but it seems like it could get the job done.
