No. MIDP doesn't include such an API. You can use LWUIT's virtual keyboard (which isn't native) and define any character set you want as explained here: http://lwuit.blogspot.com/2010/06/pimp-virtualkeyboard-by-chen-fishbein.html

You can show it using the display class.

On Symbian devices if you do not define some jad properties, a touch keypad will be always visible and you won't be able to hide it for more details look here: http://lwuit.blogspot.com/2009/11/optimized-for-touch.html

Looking at the question again I'm thinking the VKB is probably an overkill for an always on keypad replacement. Just place your content in the center of a BorderLayout and stick a container in the south something like this:

addComponent(BorderLayout.CENTER, myUI);
Container keypad = new Container(new GridLayout(2, 2));
addComponent(BorderLayout.SOUTH, keypad);
Button up = new Button("Up");
Button down = new Button("Down");
Button left = new Button("Left");
Button right = new Button("Right");
up.setFocusable(false);
down.setFocusable(false);
left.setFocusable(false);
right.setFocusable(false);
keypad.addComponent(up);
keypad.addComponent(down);
keypad.addComponent(left);
keypad.addComponent(right);
up.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent ev) {
       int up = Display.getInstance().getKeyCode(Display.GAME_UP);
       Display.getInstance().getCurrentForm().keyPressed(up);
       Display.getInstance().getCurrentForm().keyReleased(up);
    }
});

The rest and fire are pretty trivial to add (same thing) notice that getKeyCode is deprecated but should work for now since we have no alternative to that API.
