An excerpt from my "Palm OS Programming for Dummies" example in chapter 15
on dynamic interfaces:
#define Main_Form 1000 // Identifier for dynamic Form and Form
elements
Word id;
FormPtr frm;
Word firstIndex; // index of the
first dynamic Form element
// make one (or more) push buttons
frm = FrmGetActiveForm();
firstIndex = FrmGetNumberOfObjects(frm); // remember where
we're starting
id = Main_Form+firstIndex+1; // Main_Form should
be a number sufficiently large to avoid overlap
// with all
ctrl ids in the current form
CtlNewControl ((VoidPtr) &frm, id++, pushButtonCtl,
"button label", 60, 125, 10, 11, boldFont,
1, true);
// make more if needed
You'll want to keep track of the control id(s) you assign to the dynamic
buttons, so you'll be able to properly handle them in your form event
handler. You'll get a ctlSelectEvent with the data.ctlSelect.controlID value
equal to whatever you used in the CtlNewControl() call.

I'm working on it, too. The code doesn't work yet, but I know that you use
CtlNewControl.
