What language is Picasa written in?

This was asked about a year ago, but never really answered. It would be great to find out what language/gui framework was used to write Google's desktop Picasa app. Any ideas?

I had a look at the Windows version and I'd guess C++ as well for most of the components which is indicated by

• a scan using PEiD that yields that npPicasa3.dll and qtsupport.dll have been created by the Visual C++ 8.0 compiler.
• Process Explorer showing that Picasa3.exe has an open handle to MSVCP80.dll, which is the Microsoft C++ Runtime Libary
