You could even mix different languages which would allow for example the generation of interfaces by a Java-GUI builder and writing the rest of the JVM-application in C, FORTRAN or whatever (I love gcc...)

You cannot compile C->bytecode without extending the bytecode set, because bytecode doesn't
support raw access to memory (read C pointers).

Native java chips (like picojava) adds new bytecodes to support that and other related things.
