Will this project be pure DirectX?

PROJECT: A strategy game using cards

DETAILS: About 3/4 of the screen is for displaying the cards, 1/4 is the interface. The display screen is static. The player inputs using the interface. The display screen only displays the cards and doesnt do that much, its like a visualization of the cards
It doesnt have any collision, physics and the like (whatever the like is)

QUESTIONS:
1. Must the interface be built in DX too?

Sorry guys, Im kinda rushing my project, until December, and Ive got only six months for that. I can build my game as a text-based game, in dos console for example, my only prob is the graphics part..

Do you think its feasible... Share your opinions guys, but can you try not to disappoint me that much because I cant back out on the project, its my key for graduation. I cant back out on it already. please dont discourage me that i cant do it in time... pweese i beg you... thanks...
