how to get the native DC value in Tkinter/wxPython for drawing?

I am porting www.rmchart.com to python, now the code is almost
finished, and I have supplied some examples.py which write to
picturefiles directly, but the example to draw the chart on GUI stops

that is the vb declaration
nResult (LONG) = RMC_CreateChartOnDC(
ByVal nParentDC (LONG),
ByVal nCtrlId (LONG),
ByVal nX (LONG),
ByVal nY (LONG),
ByVal nWidth (LONG),
ByVal nHeight (LONG),
nParentDC (LONG) is Device context, on which the chart shall be painted

If I pass DC=ctypes.windll.user32.GetDC(0) to it, the chart is shown
on the windows, but I don't know how to get the DC in wxPython. It
seems that self.GetHandle() in wxPython does not help.

Can anyone help me?
