title: Several questions with QtCreator
body: <p>I'm working on a project which should have GUI written in Qt. I'm thinking using QtCreator as a development IDE, but there are some problems I'm facing. The project should have a dll file which shouldn't be dependent on any qt library/module, it should use only winapi and it should be compiled with both x86 and x64. So my questions are:</p>
  
  <ul>
  <li>Is it possible to use QtCreator to compile a dll which doesn't have any dependency on qt modules. If yes, how?</li>
  <li>Is it possible to use MinGW x86 &amp; x64 to compile a single project? If so, how can I specify which compiler to use?</li>
  </ul>
  
  <p>This is my first project with Qt, and I'm not a C++ guru, so please describe the details as good as you can :-)
  Your help is much appreciated.</p>
  
  <p><strong>UPDATE</strong></p>
  
  <hr>
  
  <p>Allright, I tried compiling the project as Berk suggested, but I have still a problem. The output has a dependency on LIBGCC_S_DW2-1.DLL and MSVCRT.DLL. Is it possible to remove a dependency on LIBGCC_S_DW2-1.DLL and link MSVCRT.DLL inside my exe/dll (just like MS VC does).</p>
