Question making mini-car by using mpu6050 and arduino uno r3

Hi everyone.

I want to making mini-car by using mpu6050 and arduino uno r3 .

So I ask some questions.

First question)
do make that very hard? or easy??[/b]

Second question)
I think parts like this
mpu6050 + bluetooth = remote controller.
arduino uno r3 + 2 DC motors = hardware.
thats enough? or add some parts?

I try to make that first time so not enough information

if i need some information, please tell me what is that.
