AMuleGUI
From AMule Project FAQ
aMuleGUI allows you to administrate aMuled remotely and it has a user interface that looks exactly like good old aMule. If your connection is too slow try to use aMuleCMD.
WARNING: It is still somewhat buggy (2.0.3).
NOTE: You must have External Connections enabled in order to be able to connect to aMuled.
