Depends what your application is.
 

Its recommended to go for gate driver chip that is readily available in market. This will save lots of calculations.

I have connected the MOSFET with MCU and there is some voltage between the Vdd and source but when i connect the load, the voltage immediately drops to zero.....why it happens???

It will workout
 

Can transistors(in push-pull configuration) be used for driving the MOSFET???

yes that is the simplest way, but still calculations are involved. so i suggest you to go for driver.
