Problems in using wxPython in multithreaded contextþ

For my C application, I use many interpreters (withh the fonction Py_NewInterpreter()). For my needs, I create many GUI with wxPython and I have problems. Here is My C Code:
 
{
    PyEval_InitThreads();
    Py_Initialize();

    PyImport_ImportModule("myModule");//it creates a wxApp object and a GUI (mainloop)
    ......
 
 
    Py_NewInterpreter();
    PyImport_ImportModule("anotherModule");//it should create a new wxApp and a new GUI (with Mainloop)


    .....
}
 
Unfortunately this code does not work. In fact, My C application which use many interpreters is seen by wxPython as a single application, and as wxPython is thread safe, it is not possible to create a second App. 

I have to use many interpreters to separate variables and to avoid links between modules. 
 
What could I do to create many GUI in different interpreters (each GUI have to be in a separate environment)???
 

Thanks.
