do i need a new widget?

["Gregor Waltz" <gregor waltz villanova edu>]

i am developing an application to coordinate sound files for character
animation. it is specifically oriented towards speech synchronization in
3D animations, but is general enough for other uses.

the main window will be responsible for coordinating the characters and
their sound files. i want the characters to be represented by rows as in
a list with the horizontal representing time. the sound would be
represented by movable blocks in the character rows. the blocks should
be movable so that their time positions can be changed. the length of
the block would represent its length in time. each character could, of
course, have multiple sound blocks.

do i need to write a new widget, or is there something out there that i
could adapt?

if i have to write my own widget, do any of you have suggestions as to
what tools i should use? ie widget to inherit from, gdk tools, etc. i
was thinking that a regular gtklist might be a good class to start from.

do you think that the gdk drag and drop tools would be useful for the
sound blocks?

thanks
