Unfortunately, GeoHMS tools do not manage data in GCS.  While most tools will work with it (e.g. terrain preprocessing and subbasin delineation), once you get into calculation of stream and watershed characteristics, GCS is not supported.  There are workarounds, but you are better off projecting the DEM and starting from scratch (you cannot just project all raster derivatives).
