Use events.

 

    @SideOnly(Side.CLIENT)
    @SubscribeEvent
    public void openGui(GuiOpenEvent event) {
        if (event.gui instanceof GuiMainMenu) {
            event.gui = new AwesomeMainMenu();
        }
    }

        }
    }

Can you give me a link with more documentation about forge and mainmenu interaction?
