I'm not clear on what you mean when you say "I need tool in X enviroment. So don't sujest such as vim or emacs" -- vim and xemacs are probably the two most popular editors, so it may be usefull for you to explain what it is about them that you don't like, this may enable people to make better recommendations based on your criteria.
That said, from what I've seen NEdit and Jed are probably the next two most popular.
