Yes, but there is a ton of functionality already out there, Object Pascal is popular enough to have almost everything available and for the stuff that aren't available it is trivial to call into other native languages (and there are many bindings already available). If you have a C header you can even use a conversion program that comes with Lazarus to create a binding for it. Of course it all depends on what you want to do, but for me at least that was never a problem.
