I'm using TextFieldWithAutoCompletion in my plugin. It works fine but I want to have only Interfaces (without java class etc.) in it. Is it possible to display only interfaces or make it work as in editor with implements (everything that isn't interface have red font)?

TextFieldWithAutoCompletion(PlatformDataKeys.PROJECT.getData(DataManager.getInstance().getDataContext()), TextFieldWithAutoCompletion.EMPTY_COMPLETION, true, null);

TextFieldWithAutoCompletion is for simple cases where you can enumerate the suggestions. If you want to show all interfaces, that's not so simple a case. I'd try suggest to

create JavaCodeFragmentFactory#createReferenceCodeFragment
bind it to an EditorTextField: setDocument(PsiDocumentManager.getInstance(myProject).getDocument(fragment)))
put some special user data to the document
create a CompletionContributor (please read javadoc there for details), register it with order="first", and filter out non-interface suggestions generated by standard Java completion, but only if original position file's document contains your user data from above
