bassically satire means mockingg so is the author mock a curtain group of people or he just wants the audiance laugh
If your question is asking "either/or," I think it's safe to say that Wilde is both mocking certain social conventions (marriage, femininity, class etc.) and making the audience laugh. Although the play is certainly lighthearted, the artistic genius of Wilde goes far beyond a simple laugh. In fact, the play might even be considered an exercise in understanding how to laugh at one's self--which is an important social phenomena that is actually extremely difficult to accomplish.
