With OS 3.0 and greater you can use CtlNewControl to create
dynamic controls. This should be what you're looking for. If
you want to support versions of the OS lower than that (2.x
especially), you'll have to use some code like this:
ctl = MemPtrNew(sizeof (ControlType) + StrLen(buttonStr) + 1);
// set ctl->[all properties] here
frm->objects[frm->numObjects].objectType = frmControlObj;
frm->objects[frm->numObjects].object.ptr = ctl;
frm->numObjects++;
// draw control, or redraw entire form
Note that you'll need to handle freeing the memory you've
allocated, as the OS will _not_ do it when it destroys the
form.

p.s. Eric, it would help if you described what problems
you're having and what steps you've taken to try to solve
them, instead of posting "random" one-liners without giving
anyone a clue as to what you're really trying to do.
