No, it is not currently possible for several reasons: 
   * current parser implementation is a recursive descent parser. I haven't implemented an LR parser yet, although PLY lexers and parsers are supported.
   * Syntax Directed Translator is not fully implemented either.
   * Parser Trees are supported, but there is no clear method defined for converting them into ASTs (like antlr grammars)
   * Even with AST and SDT support, a Python to C++ translator will require more complex tools and a lot of coding.

This tool is oriented to small DSLs parsing and translation; grammars like Python or C++ are too complex for the current implementation
