for i=1:32
set(handles.ithTextbox,'String',num2str(data(i)));
end

Something like:
for ii = 1:32
h_text = findobj(h_gui, 'Tag', ['X', num2str(ii)]);
set(h_text, 'String', num2str(data(ii));
end
would work if your textbox tags where X1, X2, ... , X32. You need to adapt it a little to deal with X01, X02, ... , X32.

Would this work?
for i=1:32
Tag=sprintf('X%02d',i);
set(handles.(Tag),'String',num2str(data(i)));
end
I verified. Using dynamic field name works!
