Now that we have created the same GUI using both Python's built-in tkinter library as well as the wxPython wrapper of the wxWidgets library, we really do need to combine the GUIs we created using these technologies.
Both the wxPython and the tkinter libraries have their own advantages. In online forums such as http://stackoverflow.com/, we often see questions, such as which one is better, which GUI toolkit should I use, and so on. This suggests that we have to make an either-or decision. We do not have to make such a decision.
One of the main challenges in doing so is that each GUI toolkit must have its own event loop.
In this recipe, we will try to embed a simple wxPython GUI by calling it from our tkinter GUI.
