It's not really any different than building an AST for any other
target language. There are several examples in the examples
download, and no doubt there are several in the ANTLR book as well
(I don't have it myself, so I can't confirm that though).

An ANTLR AST is always composed of tokens. If you are getting
individual characters, it can only be because your lexer is
generating individual tokens for characters and not generating
"full" tokens.
