[Chicago] using wxPython gui application in c?

[=?gb2312?q?=B7=C5=DC=F8=20=CC=B8?=]

hello,all guys,
        i am starting to make a python gui app with wxPython, and later i want to using c extension to call it.
  there is my python code(app.py):
   
  from wxPython.wx import *
class MyApp(wxApp):
 def OnInit(self):
  frame = wxFrame(NULL,-1,"Hello from wxPython")
  frame.Show(true)
  self.SetTopWindow(frame)
  return true
app = MyApp(0)
app.MainLoop()
   
  and also the c extension code
   
  #include "python.h"
//#include "wxPython.h"
#include <iostream>
using namespace std;
  static PyMethodDef g_methodDefinition = {NULL};
  #define ERROR(pyObject,msg) {if (pyObject == NULL){printf("%s",msg);PyErr_Print();exit(1);}}
int main()
{
 PyObject *pWorkObject,*pModule,*pClass,*pInstance,*pMethod;//,*pWxpythonModule;
 Py_Initialize();
 if (!Py_IsInitialized())
 {
  cerr << "can not initialize the python object!" << endl;
  return -1;
 }
 //pWxpythonModule = PyImport_ImportModule("wxPython.wx");
 //ERROR(pWxpythonModule,"cannot load wxPython.wx");
 
 //load the module
 pModule = PyImport_ImportModule((char*)"app");
 ERROR(pModule,"can not load app module!")
  .//omit some
  when the code comes to import the app module,it crashed.later with PyErr_Print,i get the error message is as follow:
  can not load app module!Traceback (most recent call last):
  File "c:\Program Files\Microsoft Visual Studio\MyProjects\runPythonGUI\app.py"
, line 1, in ?
    from wxPython.wx import *

    from wx._core import *
  File "C:\Python24\lib\site-packages\wx-2.6-msw-unicode\wx\_core.py", line 4, i
n ?
    import _core_
ImportError: No module named _core_
Press any key to continue
  though i have added the directory where the pyd lives in sys.path or the environment,it doesnot come into effect.also, as the  _core_.pyd is accompanied with _core.py and _core.pyc.and it means that it can satisfy the basic need that pyd searches the path.and i can make sure  that the problem can not come because it is a .pyd.
  any suggestions and feedback will be greatly appreciated!
  thanks ,really
  regards,
  jolley
