Answer 1

EnumChildWindows?

There could be some complications if the application is written in a non-Win32 framework such as WPF because they don't always use Win32 child controls. In that case Windows Automation is the only cross-framework API I know of (YMMV).

If you're using Visual Studio (not Express) and you're not familiar with Spy++ then fire that up and give it a go -- it's interesting if nothing else, it let's you explore the rather surprising number of windows that exist.
