Source for Crosswords -- for all versions including those that run on Linux desktop systems -- is available here.

Or you can check out the current source tree with this subversion command:

svn co https://xwords.svn.sourceforge.net/svnroot/xwords/trunk/ .

The cross-platform part of Crosswords is written in ANSI C. The Franklin- and Symbian-specific parts are written in C++, while the rest of the platforms stick to C. Ports to new platforms could use either language.
