ZeroC middleware Ice 3.4.1 has a frontend GUI for IceGrid.
I can't find it after having installed Ice-3.4.1.
I did look in the source code and did not find it. Not sure the archive contains the code.
Others distribution has RPM for it like Fedora: http://rpm.pbone.net/index.php3/stat/4/idpl/15914853/dir/fedora_15/com/icegrid-gui-3.4.1-1.fc15.x86_64.rpm.html
or Ubuntu: http://packages.debian.org/sid/icegrid-gui
or Mandrake: http://rpm.pbone.net/index.php3/stat/4/idpl/15722756/dir/mandrake_other/com/icegrid-gui-3.3.1-5-mdv2011.0.i586.rpm.html
