"ipython-qtconsole --gui qt" hangs on 64-bit win7

Running the qtconsole, then doing "%gui qt" works fine, but from the command line the window shows up but never gives a prompt.

I dug deeper into the badness, here is some more insight based on the sample output below.

• Behavior of ipython-qtconsole.exe and "pythonw ipython-qtconsole-script.pyw" is very unhelpful. It assumes users will see the message printed to the console. They will not, and just assume ipython has poor quality standards. ;) If IPython detected it was run with pythonw, it could pop up a message box instead of printing to the console in this case. This is also important for the case where dependencies like pyside/pyqt are not installed.
• Why does the ipython-qtconsole not support the --gui option? This is an option for the kernel, not the qtconsole itself, and works fine once
  you're in.

C:\>python "C:\Python27\Scripts\ipython-qtconsole-script.pyw" --gui qt
IPython: an enhanced interactive Python shell.

See #1426 for the --gui issue. I think this issue is originally just that, so I'll close it as a duplicate - you might want to open a new issue for the behaviour with pythonw.

Aside: hurrah, another Windows tester ;-). The core developers mostly use Linux or Macs, so Windows support sometimes doesn't get as much attention.
