Thats just because as soon as we have an editor, we can start to develop
lazarus with our own tools. So there is a lot of effort to get the editor
working. In stead of building our own editor we use a public edit component
already the for Delphi. To get things ported you need to be much like Delphi.

A lot of Functions/Components rely on the winapi module. Thats not only the
editor. Classes like TFont, TBrush, TPen, TBitmap, TCanvas are build upon
the winapi (this way they are compatible with routines which use api calls).
A component like TScrollbar can use just the winapi for itself so there is
no need for it to create additional (GTK and others) code to for instance
Show/Hide/Set itself.

In the beginning I don't think we are going to build all of the functions.
Just a workable set which can be extended the mment a function is needed.
