potty training issues

i had the worse time yesterday tryng to get my 2+ year old little girl to use her potty,she has become to headstrong and fiesty lately,that i dont think i  can win the battle of " so long diapers" .its just not happening for me at this time.
i happen to have a long day at work and was really extra,extra tired.after i had given her her afternoon bath and changed her into fresh clothes,she went about playing and 5 mins later...i began to percieve the dudu smell
it was horrible,i was too tired to shout,felt more like crying actually and this thus led to a 5 time change of clothes and panties
read my lips ppl five times...change
it was horrible
any tips about how to do this will be richly appreciated,i have tried begging,threatening,taking away her dolls,
but nothing seems to work
when i ask her "mama will you like to weewee or pupu"she gets really angry and shouts a big no and raises her fingers as though to warn me to leave her alone
oh!well,the hubby is usally noticeably absent from all the theatrics,,,,,,,,,,,,,hmm
