1. There is nothing much you can do customize your GUI in case of the High Label API you are using. You can't set the layout using this. For such kind of GUI you can have a look over the third party GUI like GUI.

2. You can't draw the components on the image, this kind of GUI can not be drawn using the high label,

So how can i interact with qwerty keypad if i am using canvas.

well, using Canvas for text entering can be painfull - especially when application have to run on many different devices. Maybe you should use one of graphic libraries instead of using pure Canvas (e.g. LWUIT), if this is for new Nokia devices you can consider using TextEditor object, or just display new TextBox to enter text when user clicks on your text field in Canvas (this will use native phone text entering).

First suggestions , please check the same details in the link. This can be the other solution...to check that the Form has been initialized and the theme was loaded correctly.
