Bruno,

Not sure why you mention Geotools, which is a completely different technical 
code base.
Anyway for GDAL, once your driver is developed, using a GUI that relies on 
GDAL to display your format should be pretty easy. For example you can use 
QGIS. You just have to make sure to compile against the headers of the GDAL 
version used by QGIS, and then add your plugin shared object in the path 
searched by GDAL_DRIVER_PATH. This is how OSGeo4W works for the proprietary 
formats (ECW, MrSID, etc...)
On Linux, you can also completely substitute the GDAL shared object used by 
QGIS with your own, by tweaking LD_LIBRARY_PATH and doing the right symbolic 
links (e.g "ln -s libgdal.so libgdal.so.X.Y.Z" where X.Y.Z is the version 
expected by QGIS)
Same applies for OpenEV, but the latter is probably a bit more difficult to 
build now.

Best regards,

Even
