erlang and the GUI

[info]

Hello,
Triple question:
1) I would like to display in a large multiline textbox data received from tcp socket but the GS package has only the one-line entry object ! What can I use ? the editor object ? do you know an example ?
2) Several GUI packages are available: gs,wxErlang, ...
Which one do you advice to use taking into account several criteria: support (doc,examples), standard, stability, reliability
3) And what about GUI builder ?
