Sure you can.  Just create a GMemoryInputStream or GMemoryOutputStream 
depending on the direction of the data flow between the two APIs.

If using GMemoryInputStream, in the write callback from your other API, you 
call g_memory_input_stream_add_data() (perhaps on a copy of the data).

If using GMemoryOutputStream, humm, seems like the API doesn't provide a 
callback for this one.

Regardless, you can definitely subclass GInputStream / GOutputStream yourself 
to achieve what you want.
