One of the cliches of modern business is: don't outsource your core competencies. If you are developing a text editor, you should put the time into your text editor. It's the thing that distinguishes you from your competitors. And it's the part that users interact with the most. Your users are likely to ask for features, like vi keybindings, that you can't easily build with the OS-native text field anyway. Incidental forms, like your preferences screen? Unless you have a lot of time and money to burn, the OS widgets will probably be better than yours.
