These two DLLs are located here:

  C:\Qt\2009.05\mingw\bin\mingwm10.dll
  C:\Qt\2009.05\mingw\bin\libgcc_s_dw2-1.dll

This is from the latest install of the Qt SDK, with Qt Creator 1.3 and Qt 4.6. They were indeed part of the binary SDK download.

When you distribute your application - or want to run it by double-clicking on your *.exe from within File Explorer, for example - you need to manually (or in whatever other ways) copy these DLLs into the application directory. Also refer to http://doc.trolltech.com/4.6/deployment-windows.html#application-dependencies

When you run your app from within Qt Creator (debugging) however I think these MinGW DLLs are already in the PATH. I don't remember having to copy them into my application directory while I was debugging.
