Depends on whether your app is going to have resizeable windows or not, 
and whether you're going to put it in a scrolling group, and what else 
scrolls, and ....

The way I usually start something like this is to create a graphic (just 
a box), and make it be the size (and location) I want to put the fancy 
graphics into. If I want to, I control it through the geometry manager 
(or my own geometry management).  Then I can calculate co-ords for the 
text and boxes relative to that (and even use the size if I decide I 
want to let the individual parts stretch). Then once I can see something 
"done", I might get keep the box as a background, or hide it, or remove 
it and use co-ords from the group instead, or ....

Should be - though the time to create and make visible a few hundred 
buttons shouldn't be huge anyway. And the time to make existing buttons 
visible and/or change their location should be even quicker. (Warning - 
the time to delete them can be surprisingly large - so be wary of 
deleting and recreating them).

In some ways, as a user, I quite like to see something happen - so 
having them appear as you go may be OK. If you prefer not to, use 
lockscreen and unlockscreen to make them all just "appear" at once.
