Right, but the GPL has the restriction that source must be made
available... if you are distributing via a website just put the Qt
stuff you are obligated to distribute on the site, in a separate
package, just like the distributors of GPLed stuff do with the source
they must distribute.

If TrollTech wants you to make all that stuff available, then you
really have little choice except to make it available... but I doubt
anyone will insist you package it up in the same file a your app.

Too new for that (everyone is watching to see what you do ;).
