use following code:

SPWeb web = SPContext.Current.Site.RootWeb;
web.AllowUnsafeUpdates = true;

SPNavigationNodeCollection nodes = web.Navigation.QuickLaunch;
SPNavigationNode navNode = new SPNavigationNode("Custom Menu", "#", false);
nodes.AddAsFirst(navNode);

SPNavigationNode headerLink1 = new SPNavigationNode("My Custom Page", "/MyCustomPage.aspx", true);
nodes[0].Children.AddAsFirst(headerLink1);
