It seems to me that you should be able to do this using the Constraint
Resources documented in section 6.3.2.  You need to use more of these
constraint resources, such as fromHoriz, fromVert, left, right, as well
as possibly horizDistance.  The buttons of xcalc are all placed using
constraint resources; it might be helpful to take a look at that.
