Would just using the command line be out of the question?  For example, under
Windows, you need only call netsh.exe to reconfigure a selected interface. 
For example, to change the IP address, netmask, and default gateway, something
like:

    netsh interface ip set address name="<interface_name>" static <ip_address> <netmask> <default_gateway>

Then, just spawn a shell that executes this command with the appropriate
values.  No Qt or OS APIs to locate.

Similar interface management functions might be available on other platforms
as well.
