How can I made an App without the big dll-s

If I want to send my app to another Win without QT, off course that want the QT dll files what I used.

My app want that file as well:
QtGui4 (10mb)

I'm sure, the program don't need the all from the dll.
So my question is, how can I minimize that files size?

Thanks a lot!

You need to link your program with static versions of the Qt libraries you use ; you'll have to compile those yourself first. See the documentation for details.
