You seem a bit confused as to what the target audience for this is - not unexpected given the single day the project has been online, but a topic worth discussing nonetheless. Your initial demo is to control a mouse on a Windows desktop, but in the README it states that Android will receive the first release since "desktop apps are virtually dead now." I won't pretend to know what platform this idea might take off on, and I think picking Java gave you a good set of choices, but you should nail down your stance so you and the people interested know where the project is headed.
