I running Ubuntu and Eclipse(Helios 3.5.2).
I have followed the instructions to install the Qt (4.6.1) plugins. I can see the plugins in /usr/lib/eclipse/plugins.

When I do a New Project, I do not get a Qt wizard.

When I look at the Help Menu:About Eclipse SDK:Installation Details:Plugins, I do not see "Qt Project Plug-in" or "Qt Integration Help Plug-in". (I see these on a friend's working installation)
