Can someone help me write a simple baroque style gavotte?

Hello.

Just some background about me:

I have studied 2 part counterpoint.

I can add chords to a melody like the ones in Anna Butterworths harmony in practice book.

I am working towards grade 6 theory.

I would like to write a simple gavotte in C major (easy key). I know it has to modulate and I will modulate to the dominant.

However, I don't really know how to start? Do I sketch a structure? Do I get a motif? How can I develop a motif?

I could compose 2 gavottes with the same melody, but one with 4 part harmony and the other with counterpoint.

Any pointers anyone?

thankyou
