Yes, the tool is called Windows. Just change the file extension.

GCM != ISO, its close but not the same exact format. I believe I heard there is only such a tool that can create a GCM, if you work for Nintendo

Only reason you need to make a GCM, if you are actually gonna burn it to the mini-DVD, which is something only available Nintendo developers.
