What language is Picasa written in?

This was asked about a year ago, but never really answered. It w开发者_JAVA技巧ould 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

Windows and Mac both have native apps, while the Linux version runs under Wine, so i suppose they don't use something like Java. I guess that means the Windows version is written in C++ while the Mac one is written in Objective-C.

Check out this link. Even though this API is deprecated, it suggests that Picasa's UI is coded in some proprietary XML format made by Google, with an Adobe Photoshop file as the icon.
