The easiest solution would be to use a wx.Choice. A Choice control is 
ready to be updated with new values and actually it's more what I would 
expect as user.

Radio buttons are a rather unusual solution. If you want to stick to it, 
you need to remove and add them dynamically.

Anyway, you should not try to do that in the constructor of your dialog.

To be able to access the sizer, you need to check the box "Store as 
attribute".
Then you can access it as e.g. dlg.grid_sizer1 and add a sizer using 
e.g. dlg.grid_sizer1.Add().

Just instantiate the dialog, add/remove the radio buttons to match the 
required number. You can update a button's label using SetLabel. When 
done, show your dialog.

The link you have posted, shows how to add/remove controls to/from a sizer.

How to add, you can also see from the auto-generated code:
     grid_sizer_1.Add(self.radio_btn_1, 0, 0, 0)

Also, wxGlade internally does this when you add a RadioBox (as a 
RadioBox can't be updated later on, wxGlade uses a static box plus 
RadioButtons to simulate it).
See 
https://github.com/wxGlade/wxGlade/blob/master/widgets/radio_box/radio_box.py
The methods are _set_choices and _create_button.


For more information about removing, you can look at the sizer 
documentation.
https://wxpython.org/Phoenix/docs/html/wx.Sizer.html?highlight=sizer

Look at the methods Detach, Remove, Add.


You could also use a Radiobox. On update you would need to remove the 
box from the sizer, destroy it, re-create it with the new values, add it 
to the sizer again.


wx.grid has all kinds of methods to set rows, columns and the contents. 
Just have a look at the documentation or the demo.


Also, please always use the simplest sizer that does the job. In your 
case, I would suggest to use a box sizer or a static box sizer instead 
of a grid sizer.
