[lazarus] kylix 2 (OE) -> FSF components-is it possible?

[AgentOrange]

License of kylix 2 (OE) prohibits using its IDE in competing projects (except plugins for Kylix or smth. so, I am not a loyer and English is not my native language). But it is possible to develop a component (for example, now I am
developing rich text (not rtf) control) and publish it as a GPL. Is it possible to me (or only for someone else) take this GPL-ed control and ajust to another delphi-like project? (lazarus or so).
As for lazarus, I think, gtk is not a good idea. Idea of fpgui was well, but it died.
