Does anyone know a customizeable GUI-Builder (Visual Designer, IDE-Edittor) that would allow to read & write data simply from inifiles?
Or can create custom functions as when i create a button and name it "btnExit" it would create the skeleton for events like i choose to react _OnClick and maybe on Losing focus so that it stores something as

for all controls?
it were no problem to let a function and a bit of regex, search & replace to make it to become
Callback Function btnExit_OnClick() as Long

End Function 

Callback Function btnExit_OnLostFocus() as Long

End Function
Therer are certainly gui-builders ready to use and customize available and i dont like to create it myself from scratch since that would need months.

But where to find ?
