Gui management for my device with landscape screen

[Charvi]

Hi,

I am designing an m-commerce app for my device which has a landscape screen. The problem is my screen is arranged in landscape (size: 240 x 320 ) fashion plus my device does not support touch so for intuitive GUi i have to map key to screen buttons. But whatever I do does not result into a satisfactory smart device like Gui. Can anybody point out some Gui designing and space management tips for landscape screens please. Also I am facing problem with fonts where small fonts appear too small and as I increase them enough to be comfortably visible it makes Gui appear bad. Also which font style should I use, none from the available ones seems to look decent enough on the screen !

Please help.

[ EDIT :] I also want to add some X-factor to the app. For this I added the gif animation and Graphics view animation. They look good but want something like wow factor !
