Kevin,
I've had some success using the following approach:
If you have, say, 5 pushbuttons you want uniformly aligned horizontally,
put them in a form and attach them to the top and bottom.  Then leftAttach the
leftmost button to the form, and rightAttach the rightmost button to the
form.  Then, the key thing is to make the rightAttachments of the first four
buttons to be attachPosition, using some appropriate percentage of the 
distance, and make leftAttachment of the 2nd through 5th buttons attachWidget
to the button to their left.  Then your buttons will all resize correctly.
