You can make estimates based on the application's font size. However, there
are other factors you need to take into consideration, like the widget style.
In the end, it's probably just easier to create the button without showing
it and only put it in the layout if you need to use it.

The trick is to get the button to calculate its size without showing it
first. One thing I tried was to call its adjustSize() method. This seems
to work if it isn't in a layout, but you might want to see if it works for
your buttons.
