Your code is a bit messy and hard to read (at least to me), so I can
only guess what you're trying to do.

I don't understand why you are creating the server_iochannel at all if
you don't want to read from stdin. You don't need that iochannel to send
text over a client connection. (And g_io_channel_init is not a function
you'll ever need btw).

Here's how I think you want things to happen:
 - create a tcp socket server (as you do)
 - start accepting connections async, provide a callback function
 - run a main loop
 - now, when a client connects to the server, your async_accept
   function will be called, which will give you the GTcpSocket *
   of the client which just connected
 - from the client GTcpSocket you can then get the GIOChannel
   and watch for data sent by the client via the main loop via
   g_io_add_watch(), similar to what you've done already
 - to send data, just use g_io_channel_write_chars() and pass
   the string from your text entry

Hope this helps (the GConn/GServer API might be a bit easier if you want
async networking)

Cheers
