maybe this [doc.qt.nokia.com]?

a wizard inside your project or a setup to install yours binaries on the target?

second :)
I need install binaries files

Do you need an installer only for Windows or a cross-platform installer?

cross-platform will be better, but if this is impossible than just for windows (but without linking to .NET)

For Windows, my personal preference is Inno Setup [jrsoftware.org]

On Windows I like to use NSIS [nsis.sourceforge.net]

This topic was discussed many times before. Please have a look at the tag search:

The short story: For an application you most probably want an installer for windows only. For Linux boxes you will make your users more happy with a native package (RPM, deb, …) and the Mac crowd just want’s a complete application bundle. You’ll find this discussed in detail in the mentioned forum threads.

Tnx All for the help!
