Need a layout help

[Vivaldi]

HI all ... this one gives me headache so far ... played around with it and never made it complete :-(
Now is it possible to have an monthly archive list with post title and maybe excerpt on index page!?
What I mean Index page would look like this:

October 2009
Post 1 - This is the first post
Post 2 - Second post.
Post 3 - The last one

November 2009
Post 01 for nov - Small description
Post 02 - Second description.

Any ideas!? I’m thinking this can be twisted and turned with pics and categories as well and that would give a great new blog-layout thinggy … thanks in advance for any kind of replay
