title: Download Qt sdk on windows-32 bit system: which one to choose between MinGW 4.7, VS 2010, VS 2010 OpenGL?
body: <p>I would like to download <strong>Qt sdk</strong> (libraries+ IDE Qt Creator). 
  I'm on a win-32 system but there is 3 choices for Windows 32-bit system :</p>
  
  <ul>
  <li>Qt 5.0.2 for Windows 32-bit (<strong>MinGW 4.7</strong>, 650 MB)</li>
  <li>Qt 5.0.2 for Windows 32-bit (<strong>VS 2010</strong>, 485 MB)</li>
  <li>Qt 5.0.2 for Windows 32-bit (<strong>VS 2010, OpenGL</strong>, 476 MB)</li>
  </ul>
  
  <p>What are the differences between them and which one to choose for having Qt sdk on a win-32 system ? </p>
  
  <p>Thanks in advance!</p>
