Build without any dependencies

[nateriver]

I prefer to use QtCreator ide, but don't want that libgcc_s_dw2-1.dll dependency. Anyone has any idea?

That library is responsible for new exception model ("DWARF" as long as I remember) used in gcc 4.4, which is not yet included in standard mingw, but included in mingw bundled with qt (since 4.6). If you try to compile your app using standard mingw and try to link it to qt 4.6 you'll get unresolved symbols for aforementioned reason.
So if you really want to use Qt 4.6 on Windows without that dependencies you will need to fully compile Qt itself using standard mingw (or maybe MSVC) I suppose.

P.S. I may be wrong
