Filling the available space with a column in the GridBagSizer

I am trying to create a dialogue in which there are several long descriptions, each of which is accompanied by a short question with answers using the switch. I set my controls using GridBagSizer( wxWidgets docs , wxPython docs ), in which a long description covers all three columns, and the answers to the question and two radio buttons are in their own columns.

        sizer = wx.GridBagSizer(5, 5)
        sizer.SetEmptyCellSize((0,0))
        sizer.AddGrowableCol(0)

        for i in range(5):
            description = wx.StaticText(self, -1, "This is a long description \
that may span several lines. Filler filler filler filler filler. More filler \
filler filler filler filler.")
            description.Wrap(500)

            question = wx.StaticText(self, -1, "Are you sure?")
            yes = wx.RadioButton(self, -1, "Yes", style = wx.RB_GROUP)
            no = wx.RadioButton(self, -1, "No")
