Yes, wxCrafter is inbuilt to Codelite, but especially for beginners I would wholeheartedly recommend Dialogblocks. I have tried both.
Reasons:
The implementation of GridBagSizer in wxCrafter is not very helpful.
In Dialogblocks controls can be inserted by point and click to a grid coordinate of GridBagSizer and controls can be moved by drag and drop in the grid.
(Unfortunately this is not supported for containers, in this case the coordinates must be changed manually)
It is possible to insert or remove columns and rows in a GridBagsizer, without changing all the coordinates manually.
(GridbagSizer is only available in the paid version, unfortunately, but for professional use the price is a no-brainer, and for Hobbyists it is affordable)
By pressing F5 you get instantly an accurate and functional preview of your dialog.
It has inbuilt searchable full documentation of the whole wxWidgets API, right click on a control, choose "describe" and you get full description for it including methods, inheritance, usage, portability and include file.
It can compile wxwidgets, so you can ensure compilation of your project and wxWidgets is in sync and these linkage problems that are often discussed here are avoided.
It generates makefiles for gcc and others and projects for VSStudio up to VS2017, a beta version that supports VS2019 is here:

Thats just my experience, your needs or mileage might vary.
(Disclaimer: I have only tried the windows versions of both)
If you dont decide to buy it, you can still use the inbuilt documentation and use it to build wxWidgets.
