create phonegap plugin for recording signatures

I'm currently using the JavaScript signature-pad widget to record signatures, but the touch-move event in Android's browser is too slow to update, so the signatures look jerky. I need someone to create an Android widget which, when called, will open a canvas fullscreen, in Landscape mode, with three buttons and a panel, to record the signature. the buttons should be: 1. "Clear" on bottom left, to reset the signature to blank 2. "Finish" on bottom right, to return the signature data to the JavaScript 3. "Cancel", to simply clear the widget from the screen and return to JavaScript the signature data should be returned as an array of lines, each line having 4 coordinates (x1, y1, x2, y2).
