#include <Xm/Xm.h> 
#include <Xm/PushB.h>

/* Prototype Callback function */

void pushed_fn(Widget , XtPointer , 
               XmPushButtonCallbackStruct *);


main(int argc, char **argv) 

{   Widget top_wid, button;
    XtAppContext  app;
   
    top_wid = XtVaAppInitialize(&app, "Push", NULL, 0,
        &argc, argv, NULL, NULL);

    button = XmCreatePushButton(top_wid, "Push_me", NULL, 0);

    /* tell Xt to manage button */
				XtManageChild(button);
   
				/* attach fn to widget */
    XtAddCallback(button, XmNactivateCallback, pushed_fn, NULL);

    XtRealizeWidget(top_wid); /* display widget hierarchy */
    XtAppMainLoop(app); /* enter processing loop */ 

}

void pushed_fn(Widget w, XtPointer client_data, 
               XmPushButtonCallbackStruct *cbs) 
  {   
     printf("Don't Push Me!!\n");
  }

According to the subject you are looking for the motif header files. 
They are not needed to run applications but only if you want to compile 
something which wants to include the motif library. The header files are 
therefore part of the development package "libmotif-dev".
