I just wanted to know can i use 1 port on any switch as a trunk and will able to terminate it on to 1841 and can make virtual interfaces. Is this possible

it should be possible. i've heard of some IOS versions (on the router side) not supporting interface trunking though.
You will need to trunk your two switches together. Then trunk the router to one of the switches. Subinterfaces on the router will do the inter-vlan routing. It's usually referred to as a "router on a stick".

Hi Imran,
IOS version 12.4 actually supports dot1.q trunking for 1841 routers.
Reference is the Feature Navigator:
