Check out the DCC-EX website............................... Lots of great ideas/plans for physical throttles too if you don't want to use a cell phone or JMRI.
Sorry, a little late, just saw this today and thought I'd mention a few options if anyone is looking for a physical wireless throttle. It is very easy and inexpensive to add a physical throttle knob now to a phone throttle ....
..... I have print files up to help with that but....
....even without a printer you can easily build something as shown above. More on all of that here and also the print file link ....

The throttle above is a little harder to build and you will have about $50 in one but it works great and has most of the options of a commercial one.....
.... can run multiple engines at the came time and/or consists and you can program the keys or any other buttons you want to add. Does require soldering skills but can be built in a day. I love mine and built a second one and don't touch the phone throttle anymore.
The hardware/software designer is Peter Akers who also did EngineDriver so has a lot of features and can easily handle 28 functions via the keyboard or added buttons or both. More on how to build it, print files and shopping list here ....
