You'll probably need to write some code that adjusts the grid column 
widths to fill the space given the grid.  Check the wiki and also the 
list archives as this has been discussed before so there are probably 
some examples somewhere.

Part of the problem is how you are using the sizers.  You are Fit()ing 
the panel to be large enough to show all the widgets, but you are not 
doing anything to the frame to make it large enough.  So the grid is 
drawn off the edge of the frame and you can't see some of it unless you 
make the frame larger.  One way to handle this is to do this instead of 
your SetSizerAndFit:

     panelA.SetSizer(mainBoxSizer)
     mainBoxSizer.SetSizeHints(self)

That will not only make the frame start out to be large enough to show 
all the widgets as dictated by the sizer, but will also limit it from 
being resized too small.

It is not to the right of the grid, it is the grid.  That is simply how 
the grid displays itself when its size is larger than the width of its 
columns.  Since you are putting it into the sizer with a proportion of 1 
then the sizer will give it an equal share of all the extra space, so it 
will size the grid larger and larger as you resize the containing window.
