I'm not exactly sure we're on the same page.  The term "default button" 
has a very specific meaning in Windows -- it is the button that fires 
when you hit Enter in a dialog, whether or not it has the focus.  It is 
the "OK" button for the dialog.  Spacebar fires the button with focus, 
which might or might not be the "default button".

The default button has a thicker border at all time, using the default 
button highlight colors.  A button with focus gets a slightly thicker 
border and a dotted line around the button text.

Some of this can be changed by the Windows XP theme, but if you want 
something fancier than that, you'll have to use an owner draw button.
