to get fields from different line to a single line

input:

field1
field2
field3 field4

output:

"field1";"field2";"field3";"field4"

My input file is shown above and I want output as shown using awk. the length of field3 is fixed so, the space between field3 and field4 can vary according to the value of field3. I am new to unix, so can anyone please help me.....
