Applets, Stand Alone and Mobile Devices

I'm looking to make an MMO.  I want it to be a stand alone application with good quality graphics (Better than WoW).  Out side of that, I want to be able to access certain aspects of the game in a browser window / applet, tradeskill / harvest, etc, and perhaps a low quality graphic representation of the world as well (comparable to Runescape, worse is even acceptable).  And finally much further down the line be able to have a few of the game aspects accessible by mobile phone or similar device.

I am figuring that the highest chance of success with this would be with Java, and for at least the stand alone portion, jME.  Is that a fair judgment?

Thank you so much in advance.
