The screenshot above is on top of NetBeans IDE 7.1.1, so the iReport plugin above fits into it without a problem. You'll need more than the plain NetBeans Platform, since the iReport plugin also makes use of the Component Palette and the Welcome Screen, for example, both of which are not part of the NetBeans Platform. But after a bit of figuring things out, you'll end up with a result similar to the above.
