Have a look at Toad (if you haven't come across it already):

http://www.quest.com/toad-for-mysql

It is a very powerful and freeware Win32 MySQL editor/manager.

It's a 19MB download, but it's an excellent tool.

I especially like the SQL Modeler, which allows you to 'Quickly create the framework for a SQL statement from a graphical interface, including selecting tables and views; selecting and joining columns, adding conditions, etc'.

SQL modeler is similar [read: a clone] to the old stand-alone Microsoft Query tool, and the graphical SQL view interface available within MS Access. Very nice.

There is lots more to explore with Toad, but the SQL Modeler alone makes it worth the download, IMHO.
