Well you can use the X11 X-Test extension to generate synthetic mouse
events. If you want to give it a try:

---snip---

#include <stdio.h>
#include <X11/extensions/XTest.h>

int main (void) {
	Display *display;
	int BtnNr = 2; // middle mouse button

	if( !(display = XOpenDisplay(NULL)) ) {
		fprintf(stderr, "unable to open display\n");
		exit (1);
	}

	XTestFakeButtonEvent(display, BtnNr, False, 0);
	XTestFakeButtonEvent(display, BtnNr, True, 0);

	XFlush(display);
	XCloseDisplay(display);
	exit (0);
}

---snap---

gcc source.c -o source -L/usr/X11R6/lib -lX11 -lXtst

I think using the XTest extension should be your second
thought too ;)
