… ok i did it with just some additional .php-files – without any maps-plugin.
there’s an easy to use description on the “google developers”sites:

there was a problem with “none utf-8” in my database but i solved it with a simple “mysql_query(“SET NAMES ‘utf8′”);” tag when opening the connection to the MySQL server in the outputting file.
to bring the map to the blog just use “<iframe src=… “
works fine!
