QT in linux ?

[a.s at clix.pt]

hi.

i am developing a project using pd/linux. i am fairly
new to this universe (linux particularly) 
but i have experience in such env. like pd (max).

i was wondering if is there something in linux similar to QuickTime.
i need to acess a built in synth ... those of you who know max might
know the qt object by david z. which acesses qt synth ...
am i dreaming ? or do i have to purchase a synth and noteout it ?

thanks, sier.
