Snippit from Palm OS Programming for Dummies example:
#define Main_Form 1000 // Identifier for dynamic Form and Form
elements
//
// Create the main form dynamically
//
static void MakeMainForm(void)
{
FormPtr newForm;
EventType openEvent;
newForm = FrmNewForm(Main_Form, "Tester", 0, 0, 160, 160, false,
0, 0, Main_MenuBar);
FrmSetActiveForm(newForm);
FrmSetEventHandler(newForm, MainFormHandleEvent);
// add dynamic interface elements
CtlNewControl ((VoidPtr) &newForm, Main_Form+1, buttonCtl,
"Next",
20, 145, 40, 14, stdFont, 0, true);
CtlNewControl ((VoidPtr) &newForm, Main_Form+2, buttonCtl,
"Previous",
100, 145, 40, 14, stdFont, 0, true);
// generate event
openEvent.eType = frmOpenEvent;
openEvent.data.frmOpen.formID = Main_Form;
EvtAddEventToQueue (&openEvent);
}
This example does more than you need, making a form and buttons, but you get
the idea... just be sure to give new buttons an Id.
In your form handler, you'll need to use:
case ctlSelectEvent:
switch(event->data.ctlSelect.controlID) {
case Main_Form+1:
break;
case Main_Form+2:
break;
}

Subject: Dynamic Button Creation Crazyness...
Howdy all,
I can create dynamic buttons. I can even see them. I don't
seem
to be able to click on them though (meaning, they don't invert like the
buttons you build in Code Warrior's constructor do.).
Do I need to do something special to be able to use dynamically
created buttons?
