This should be no problem. I'm currently out of office and will check that next week.

FYI: I started creating makefiles for the MinGW compiler - GKS already working fine.I ask for patience ...

I drop the request (with a success), as gr is now available via Christoph Gohlke.

Q: next try is not promising: http://gr-framework.org/examples/double_pendulum3.html
A: I will check this.

Q: example is not valid python 3 syntax: http://gr-framework.org/examples/figanim.html
A: Has just been fixed in the master branch.

Q: http://gr-framework.org/examples/pyqt4_ex.html gives error ...
A: The GR bdist was not built with Qt. Possible reason: missing Qt SDK or QTDIR specification.

For the impatient user - here you can download a portable Windows GR application (including Python 2.7, Qt 4.8.5, wxWidgets 2.9.4, GhostScript 9.06):

http://pgi-jcns.fz-juelich.de/pub/Downloads/gr-0.10.0-win32.zip

You simply have to change the path in gr/gr.bat, e.g.

set GRDIR=C:\gr

apparently qtplugin.dll is not shipped with Gohlke's http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4
I don't guess how it should comes down to my installation

is creating the image but also this output on spyder internal console (not sure if it is to expect, suspect a python3+windows compatibility issue):

my system doesn't understand the exec input line in http://gr-framework.org/examples/qtgrdemo.html

    @QtCore.pyqtSlot()
    def _shellEx(self):
        input = str(self._shell.text())
        exec input
        self._shell.clear()
        self._gr.update()

this example fails http://gr-framework.org/examples/textonaxes.html

there are wheels for "gr" from Christoph Gohlke, so the original issue is droped.
I'll open separate issues for the other remarks, after redoing tests.
