Hi. You can draw regular polygons with the RegularPolygon handler. See the regular-polygons.html example. You won't be able to use WMS GetFeatureInfo to get features outside of/contained in/intersecting a polygon, as GetFeatureInfo only supports x, y parameters. You may want to look at what WFS GetFeature can provide you.
