Have a look at AT-SPI; it may be overkill, but it allows you to see 
pretty much everything that's going on in the desktop.

http://gnome.org/~billh/at-spi-idl/html

There are python bindings for AT-SPI available too, for instance see 
gnome svn modules 'orca' for an example of a sophisticated at-spi client.

You can also look in svn module at-spi/test or svn module at-poke to 
find smaller, c-based clients.

The "root object" in the AT-SPI hierarchy has a single child 
representing the 'desktop', and each of its children in an object of 
AT-SPI type "Application".  The children of the Application objects are 
Accessible objects corresponding to the toplevel windows on the 
desktop.  AT-SPI also provides some device snooping API so that you can 
detect mouse and keyboard activity.
