well, if you already know "ha" (you could look it up on a hiragana chart somewhere) you just add a choing choing to it, which is just two little dashes to the right of the character- kinda like ("). ha with a choing choing is ba, then you add ka to it (look that up too). If your computer can read Kana, it looks like ばか
Baka is usually writen in the form of writing used for foreign words, katakana. If your computer can read kana, its usually written like this: バカ The term is also sometimes written with kanji (Chinese characters) and comprises the symbols for horse and deer, respectively, thus 馬鹿.
This is an incomplete sentence, in Japanese pronouns are usually omitted and assumed depending on the context, so this can mean 'I/he/she/they/etc are/am/is/ stupid'.

If you insist on using 'baka' then it is followed by 'na' instead of 'no'. "Wo" is a completely different case, it is an accusative particle (a particle used to show 'object' of a verb), so your phrase would be 'watashi no baka na tomodachi'.
I believe you are thinking of the finale of the William Tell Overture by Rossini. :)
ばかな子供 (baka na kodomo) would mean "stupid/foolish kid/children" in Japanese. Idiotic little brat would be 'baka na gaki' and for little girl replace 'gaki' with 'komusume'.
