Sure, happens all the time. Bind an event handler to the map, and create 
a callback function to handle the event. Here's an example:

map.events.register('click', map, handleMapClick);

function handleMapClick(evt) {
   // don't select the point, select a square around the click-point
   var clickbuffer = 18; //how many pixels around should it look?
   var sw = map.getLonLatFromViewPortPx(new 
OpenLayers.Pixel(evt.xy.x-clickbuffer , evt.xy.y+clickbuffer) );
   var ne = map.getLonLatFromViewPortPx(new 
OpenLayers.Pixel(evt.xy.x+clickbuffer , evt.xy.y-clickbuffer) );

    // open a popup window, supplying the coords in GET
     var url = click_url + '?bbox='+sw.lon+','+sw.lat+','+ne.lon+','+ne.lat;
     window.open(url,'popup');
}
