You can use code such as:

FindWindow(wxID_FORWARD)->Disable();

Right - but those controls can be incorporated onto a panel that
provides additional user feedback such as a progress bar - and just
disable the Next/Finish button until the import has completed.

I don't think so, if it's designed nicely.

There's no reason we cannot extend the class anyway, to provide
cleaner access to the buttons etc.

Please bear in mind that there are likely to be more wizards in the
future (for example, to aid replication setup). Whatever you do here
also defines the style of those future wizards as we don't want to
have differing look and feel between them. Therefore, I would suggest
you need to keep things as simple as possible and only deviate form
the wxWidgets way of doing things where absolutely necessary.
