yes it is possible to come from UAE or KSA to Qatar,
as indian national she can get visa on arrival at Qatar Airport,
how ever she would not have direct flights so she has to either take oman air or kuwait airways to come to qatar via oman or kuwait,
my friend just visited me from saudi this week he had to take kuwait airways and come via connecting flight from kuwait,
so it is possible just ask her to book oman air via muscat or kuwait air via kuwait.
all the best
