Sure, but the names being different means that an OL Developer probably
can't tell you the exact things you should be using in GWT.

yes... and you're looking for the names to call... which is what I can't
give you...

 vectorFeature.geometry.transform(new
 OpenLayers.Projection("EPSG:4326"),  new
 OpenLayers.Projection("EPSG:900913"));
