non-wordpress mysql database integration google calendar?

Hello,

Essentially what I would like to do is integrate a separate mysql database (or a set of tables from this database, I could easily import them into the main wordpress database used for the blog) that would be accessible from within a blog page itself. Additionally, I would like to be able have items within the google calendar displayed dynamically by calendar date entered into the mysql table (the entry page would be a password-protected non-wordpress page for internal use only, but I would like to display updated information on the blog via the calendar).

So basically, what I have installed already is wordpress + google calendar plug-in. What I need is:
1) a way to connect the mysql database and/or tables not currently in wordpress to the wordpress blog such that I can query and display information from these tables dynamically and
2) also connect the google calendar app to this non-wp database/tables via a query that would display an updated listing of information by calendar date (it’s for deadlines, so for example I’d want to display everything due by the date entered in the database in chronological order).

My guess is that #1 is easy and #2 more difficult. My main question is what is the best method for doing either of these (any ideas or suggestions welcome) and/or does a plug-in already exist? How can I connect the non-wp to the wp db or tables and query from within a new wp page? Would be lovely if I could just write the php code directly in the edit box………
