More builders for easy instantiation of classes with many default arguments in ctor

[kenz-gelsoft]

I made builders for some GUI classes used in porting sample code.

In #119, many new classes are generated, without builders. More builders may be required(or requested).

For a while, I'll make new builders per request (by users, mainly me)

Specifying these may be required to generate builders semi-automatically

• Ctors used for builders
• Stable parameter names (which converted to method names of builders)
