Yes.

markers = new OpenLayers.Layer.Markers("zibo");
map.addLayer(markers);

feature = new OpenLayers.Feature(layer, 
                           new OpenLayers.LonLat(0,0));
marker = feature.createMarker();

markers.addMarker(marker);
marker.events.register("mousedown", marker, function(evt) {
     if (popup == null) {
         popup = feature.createPopup(true);
         popup.setContentHTML("<a
href='http://www.somethingconstructive.net' target='_blank'>click
me</a>");
           markers.map.addPopup(popup);
       } else {
           markers.map.removePopup(popup);
           popup.destroy();
           popup = null;
       }
       Event.stop(evt);

});

marker at 0,0 with a popup with a link inside.

(From http://openlayers.org/dev/examples/popups.html )

Next version will probably have popups like:
