The x,y returned by the translation depend of the coordinate system of the raster (returned by GDALGetProjectionRef()). For a geographic coordinate system, generally you get x = longitude, y = latitude. For a UTM projection, x = easting, y = northing. For other projections, it depends on the units of the projection system. For conversion between coordinate systems, you're interested in OSR then.
