Above are the APIs for both Yahoo and Google Maps. I understand
Yahoo's is more powerful (and their Terms of Use are less
restrictive), but I believe both require javascript. If your looking
for something without JS, I'm not sure what to tell you (although I
could be wrong on that point). I do know that quite a community has
developed around hacking up Google maps, so a quick search should give
you lots of info there. I suppose the same is true of Yahoo among its
fans as well.

After a quick look through some examples on the Yahoo application
gallery, I found this, which appears to do something similar to what
you want for the Wordpress blog.:

Btw, that page points to
http://toys.lerdorf.com/archives/35-GeoCool!.html which has lots of
php code using REST to get the map and data. So maybe you don't need
JS after all. Although I didn't read through is real closely and I saw
some references to Flash. But, hey its a start.
