Ok, I have finally made it.

If anyone cares, I've used
org.mozilla.browser.impl.jna.Gdk
org.mozilla.browser.impl.jna.Glib
org.mozilla.browser.impl.jna.Gtk
org.mozilla.browser.impl.jna.LibC
org.mozilla.browser.impl.jna.X11
from MozSwing project.

and I used this function to create handle, also taken from MozSwing
with little changes.

 public long createHandle(Rectangle dim) {

          long mozHandle=0;

          Toolkit.getDefaultToolkit().sync();

          //  HANDLE FROM CANVAS NATIVELY OBTAINED
          int hw = (int) getHandleCanvas();
          X11.Window awtID = new X11.Window(hw);

          Gtk.gtk.gtk_init(null,null);
          Gtk.gtk.gdk_error_trap_push();

          gtkPtr = Gtk.gtk.gtk_window_new(Gtk.GTK_WINDOW_POPUP);
          Gtk.gtk.gtk_window_set_default_size(gtkPtr, 300, 300);
          Gtk.gtk.gtk_window_set_title(gtkPtr, "Mozilla Wrapper
Window");


          Toolkit.getDefaultToolkit().sync();
          Gtk.gtk.gtk_widget_set_usize(gtkPtr, dim.width, dim.height);
          Gtk.gtk.gtk_widget_show(gtkPtr);
          Toolkit.getDefaultToolkit().sync();


          X11.Window gtkID = Gtk.gtk.gdk_x11_drawable_get_xid
(gtkPtr.window);
          GdkDisplay display = Gtk.gtk.gdk_display_get_default();
          X11.Display xdisplay = Gtk.gtk.gdk_x11_display_get_xdisplay
(display);
          X11.INSTANCE.XReparentWindow(xdisplay, gtkID, awtID, 0, 0);

          mozHandle = gtkPtr.getPeer();


return mozHandle;
	}
