You are likely going to need to do it with a render controller and custom model.

To get you started :

Model

public class NewsListingModel : IPublishedContent
{
    public IEnumerable<string> Categories { get; set;  }

    public IEnumerable<YearArchive> Years { get; set; }

    public class YearArchive
    {
        public int Year { get; set; }

        public IEnumerable<int> Months { get; set; }
    }
}

Controller

public class NewsListingController : RenderMvcController
{
    public ActionResult NewsListing(BlogListingModel model)
    {

        model.Years = model.Content.Children.Select(x => x.CreateDate).GroupBy(d => d.Year).Select(y => y.FirstOrDefault()).Select(y =>
            new NewsListingModel.YearArchive
            {
                Year = y.Year,
                Months = model.Content.Children.Where(
                x => x.CreateDate.Year == y.Year).Select(
                    x => x.CreateDate.Month
                    ).GroupBy(mg => mg).Select(m=>m.FirstOrDefault())
            });

        return CurrentTemplate(model);
    }
}

You could then then making an archive content type which takes a int month and int year parameter to a controller to filter the children of the node you are after?

Or you could extend the model further so it all happens on the same page?
