This may well be what a sane person would think after perusing the
license text, but you need to be aware that the FSF takes a much more
expansive reading of that text. AFAIK those details haven't been tested
yet in any court of law --- but until a reading is settled by court
precedents, people tend to look to the FSF's interpretation. And the
FSF is on record as saying that if code A depends on code B then B's
GPL license infects A, even for pretty weak values of "depends".
You should carefully read http://www.gnu.org/licenses/gpl-faq.html,
which contains statements such as
If the program dynamically links plug-ins, and they make function
calls to each other and share data structures, we believe they form a
single program, which must be treated as an extension of both the
main program and the plug-ins.
I don't have anything against the GPL's goals, but those goals are very
clearly that the entire software universe should be GPL code. If that's
not what you have in mind, then you should think twice about licensing a
software component (as opposed to a standalone product that isn't meant
to have other code depending on it) under GPL.
