You can have a "shortcut" to anything, but you also need to consider where from.
From
Sys Menu - Wad full channel, Wad forwarder - requires a banner
HBC - Sometimes a dol with instructions, or somtmes an xml arg - easy peasy hbc icon.png and some writing, good for instructions EG A=thing, B-thing2 etc
Loader - An iso containing the dol - cover (note words can be read from a cover for complex loadings)
Stored
On..nand, SD, HDD, WODE
, Disc*, SMB*
*I'll stop here and not go on, they can get more cleverer, or stoopider
Once you get a standard template for one, keep a hold of it. Most times a hex editor can be used to select easily change what it loads. Or you can swap the dol.
So being simple if you want 1 game from sys menu get CRAP, it makes WADs. Install, done.
If you want to make if from HBC you can extract that WAD using customisemii for a 1 game dol.
To make an iso there are many ways and many tools, but wii wiiscrubber or wimms tools would do and you replace the main.dol with yours.
If you wanted something more complex, explain where you want to load it from, and what you want it to load into and any details.
You're best to get devkit imho...
You can make them quite complex, EG it loads a loader if nothing is held, if A is held load Doshin from wode, if b is held load SSBB from the Wiis usb hdd or B on a gc pad to load the smae game with cheats, hold 1 and maybe it loads gbatemp new releases using an installed opera or a full screen flash game, hold 2 and load a specific gba, nes, snes rom etc. But hold A on a gc pad loads a specific gc game, maybe doshin again but with cheats enabled ? or Y is a vc game on nand2 no cheats, x nand2 and cheats, z same game again but nand3...fook that games popular
