   1. Panels are "containers" - they combine different components
   together into one Window, so that you can pass the panel as a parameter =
to
   other functions. For example, if you wanted to create a popup menu, you
   would have to specify which panel the menu is in. Although at first pane=
ls
   may not make sense, looking at examples is very helpful. There are plent=
y on
   the wxPyWiki.
   2. Menu creation is documented very well in the tutorials on the wiki;
   just search for "menu." There's a lot more information out there about m=
enu
   creation in wxPython than I can contain in this one message.

Here is a sample snippet of code that shows you how to make a File -->
CreateFile menu (although I think "New" is a better title than
"CreateFile"). I am assuming that you are putting this code in a class that
derives from wx.Frame - this way I can type self.Bind() instead of
frame.connect() for the event binds.

menubar =3D wx.MenuBar() # The menu bar
filemenu =3D wx.Menu() # Creates the "file" in the menu
filecreate =3D filemenu.Append(101, '&CreateFile', 'Create a file') # The 1=
01
is an ID, and the '&' tells you which letter to underline
menubar.Append(filemenu, '&File') # Add the filemenu to the menubar

self.Bind(wx.EVT_MENU, self.OnNew, filecreate) # Bind the function
self.OnNew to filecreate

...

def OnNew(self, e):
     pass

You see that I put pass in OnNew. What you want is called a FileDialog, and
it looks like the native file creation dialogs. Again, there's more
information about it in the documentation and the wiki.
