From the developer:
wxDesigner is a tool written to make creating dialogs for wxWidgets based programs easy and fast. wxWidgets is a cross-platform toolkit and it thus cannot make use of native resource formats as they typically exist for many platforms.
For that reason, wxWidgets has been optimized over time to make writing dialogs by hand as easy as possible, but this approach has limitations as soon as dialogs reach a certain complexity.
