What's wrong with DCHakker? There's also DemoMenu but you probably wouldn't like it's GUI either.
There's also Dream Inducer and a Windows program that uses SBI packages which are the DC homebrew program (e.g. NesterDC) with details about it's release, which Dream Inducer uses. You may wanna check it out, it's called Selfboot Inducer and the download can be found at the SBI repository:
