Via the OSGeo-Discuss list I learned about the release of the open source library MapQuery 0.1. Here's the official mapquery website.
What is MapQuery? "MapQuery is a pure javascript based library which builds upon OpenLayers, jQuery and jQuery UI to provide an easy to use webmapping library. It is meant for jQuery application developers who want to build Rich Internet Applications (RIAs) with maps. Currently it provides a few basic widgets to create functionality around a map and an easy API to write your own widgets."
Here's more on its goals: "MapQuery formally extends OpenLayers, it is similar in concept as GeoExt, but uses jQuery instead of Ext. The idea is to create a jQuery-style webmapping library which wraps around OpenLayers and extends it with functionality like layer managers, datagrids (NYI), legends etc. We try to make it easy to create a webmap-application with OpenLayers, without having to know all that OpenLayers has to offer.
We aim at jQuery developers more than on people who are already well-versed in OpenLayers. As such we will provide a few simple functions which (we think) will be enough for 90% of the use-cases. The other 10% is not actively pursued, though one could directly access OpenLayers and do some of the advanced stuff we're not providing."
