I would like to see what blocks some files are using. I am talking about files being stored on disk, not blocks in memory. Is this possible in Windows 7?

It's possible to get this information using FSCTL_GET_RETRIEVAL_POINTERS, see the article on Defragmenting Files for more information.

Windows does not come with any program that can show this information, so you'll have to either write your own, or try various third-party defragmenters – I have seen one of them having an option to show the on-disk layout for any file; I just cannot remember which.
