If you install the standalone version form
http://www.gisinternals.com/sdk/
make sure it has no red warning in the line where you download

If you execute the SDKshell.bat inside the directory, gdal points to 
that standalone version. Exiting that shell, everything is back to normal.
You can transform your raster from ecw to something other in the shell, 
then proceed the result with Qgis the normal way.

Its just a workaround as long as the ecw driver in osgeo4w does not work 
properly with osgeo4w gdal.
