Yes I found the QGIS plugin in here: http://pyqgis.org/repo/contributed, but how can I use it in Windows 7? I think it is source, only for Linux. Are there any instructions for applying it in QGIS in Windows?

Yes, this is normal. You can't see any geometries because you're
dealing with raster data, not geometry data. But you can use the QGIS
WKTRaster plugin, from here http://pyqgis.org/repo/contributed. This
is the direct link
