Okay, here are the steps as I know them:

- Create an IGeoResource from your image
- Create a Layer from your IGeoResource
- Add the Layer to the Map

I will let Jesse explain how to create the IGeoResource -- ultimately 
you want an instance of WorldImageGeoResourceImpl, but this is an 
internal class, so there would be a better way to obtain it...

As for the last steps:

Create a layer from the IGeoResource:
IGeoResource pngGeoResource;
ILayer layer = pngGeoResource.resolve(ILayer.class, null);

Obtain the map:
ApplicationGIS.getProjects().get(0).getElements(IMap.class).get(0)

To add the layer to the map:
map.sendCommandASync(new AddLayerCommand(layer) );
